This lab entertained the idea of projectile motion and how, at different maximum heights and velocities, an object can fly shorter or farther distances. The point of the lab was to find the initial velocity of the projectile launched, as well as the final distance it reached.

Topics and ideas that were key to this experiment include: normal force, air resistance, the work energy principle, the momentum priciple, and the idea of uncertainty. Procedure. The first step was to set up the launcher at an angle of 0 degrees.

A ball of mass m was then loaded into the cannon and pushed back until one click was heard. The reason behind stopping at one click, is that two or more clicks may add too much power to the shot, sending the ball on a dangerous path of destruction.

## Projectile Motion Conclusion Essay

After prepping the launcher, two meter sticks were obtained and laid flat on the ground, end to end. The meter sticks were then kept in place by use of duct tape. Once the meter sticks were locked into place, two sheets of paper were placed on the ground in places where the ball was thought to land after launch. Finally, the pieces of paper were overlayed by pieces of carbon paper to allow the shots to be measured after impact.

The second part of the experiment was just a repeat of the first, except the launcher was set at an angle of 30 degrees. Data Collection. Constants â€”. Initial Height â€” 1. Mass of Ball â€” m. Gravity â€” 9. Data Modeling. As previously stated, the point of the lab was to find the initial velocity of the projectile after launch. Once the data was collected, either the work energy principle or the momentum principle can be used to figure this out.

The Work Energy Approach:. So, what do we know? Well, we know that the work energy principle states that. With this in mind, we also know that.Set up a ramp at an angle of about 10 degrees so that the ball will roll off, then roll about 10cm on the table and fall off.

Then, set up the photo gates 8 to 10cm apart but still allowing the ball to roll through them when it goes off the ramp then falls off the table. Through this lab, I was able to examine the affect of forces on the trajectory of a moving object. It also gave me experience using the photogate probe ware and more experience with logger pro. This will help me get a better understanding of the force of air resistance. You actually have excellent writings. Thanks a bunch for sharing your web site.

If you were to drop a ball, releasing it from rest, what information would be needed to predict how much time it would take for the ball to hit the floor? What assumptions must you make The velocity, and the height of the drop. If the ball in Question 1 is traveling at a known horizontal velocity when it starts to fall, explain how you would calculate how far it will travel before it hits the ground.

A pair of computer-interfaced Photogates can be used to accurately measure the time interval for an object to break the beam of one Photogate and then another. If you wanted to know the velocity of the object, what additional information would you need? The direction of the object ,and the distance between the photogates.

Hypothesis: If gravity is normal power, then the ball launched from the ramp will land about 10 cm from the floor origin. Make sure that the photogate plugged into DIG1 is closest to the ramp, but not on it. Mark a point on the ramp to roll the ball from each time. Roll the ball down the ramp, through the photo gates, and catch the ball before it hits the ground. Open the file 08 projectile motion on Logger Pro. Enter the distance in meters between the photogates. Measure this using a meter stick.To determine the maximum height of projection as a function of the angle of inclination.

To determine the maximum range as a function of the initial velocity. Projectile is defined as, any body thrown with some initial velocity, which is then allowed to move under the action of gravity alone, without being propelled by any engine or fuel. The path followed by a projectile is called its trajectory.

A projectile moves at a constant speed in the horizontal direction while experiencing a constant acceleration of 9.

To be consistent, we define the up or upwards direction to be the positive direction. Therefore the acceleration of gravity is, Horizontal motion of projectile The speed in the horizontal direction is 'vx' and this speed doesn't change.

The equation which predicts the position at any time in the horizontal direction is simply. Vertical motion of projectile Because gravity has a downward pull, the vertical velocity changes constantly.

The equation that predicts the vertical velocity at any time 'vy' is. The 'Voy' is simply the original velocity in the vertical or y-direction. To calculate the position in the y-direction, the full distance formula must be used. Acceleration for projectiles near the Earth's surface is We don't re-write the equation with a negative sign. Rather, we use the negative acceleration value when solving problems.

When a projectile is launched horizontally a ball rolls off a table, a car runs off the edge of a cliff, etc. Here the original y-velocity is zero. Either works out the same. Velocity To determine the total velocity of a projectile, we combine the horizontal velocity 'vx' and the vertical velocity 'vy' using the Pythagorean Theorem. At maximum height At the top of its path, the projectile no longer is going up and hasn't started down, yet.

The only velocity it has is just its horizontal velocity, vx. Remember, the horizontal speed stays constant throughout the projectile path. A common misconception occurs at the top of a projectile's arc. When asked what the acceleration of the projectile is at this point, many people answer "zero".Projectile Motion Purpose: An object in a projectile motion move horizontally with no acceleration and vertically with the gravitational accele There is a little drop off at the end of Introduction In this lab the main focus was projectile motion.

In doing so, we determined the initial velocity of the ball shot horizontally from the spring loaded projectile launcher. Also, we verified the angle at which the projection of the ball would produce a maximum range. Lastly, we predicted the range that a ball would travel at a certain angle, theta. Projectile motion is the motion of objects that are initially launched, or projected, and then continue moving with only the force of gravity acting upon it.

The forces involved in projectile motion are the initial velocity of the projected object at a certain angle and gravity acting downward on the object. The vector nature of forces can be used to determine how far an object launched can go and its initial velocity at an angle of 0 by finding its x and y components separately.

The components of velocity are found by taking the initial velocity multiplied by sin for the y component, and cos for the x component. Also, the time of flight can be found. After solving for t, we find that the ball is in flight for 0. The procedure to find all the values varied to find each one. First, to find the maximum range at which the ball travels, the ball had to be fired at various angles.

After doing so, we found that an angle of 45 produces that greatest range. Second, to find the initial velocity we fired the ball completely horizontally and measured how far it went and used the initial velocity to find the resulting initial velocity. While determining the angle of maximum range, we used the launcher to shoot the ball at different angles, starting at 30 degrees and increasing by 5 degree increments up to 50 degrees, and then determined the point at which the ball landed for each angle of projection.

The measurements are as follows: Angle of Projection Range of motion m 30 2. If you fire the projectile launcher at some angleyou can analyze its horizontal and vertical motion independently of each other. The angle we chose for this part of the experiment was 55 degrees.

Our data is as follows: Trial Range m 1 2.Thursday, October 20, Projectile lab. When you throw a ball, the ball tends to be in motion. Such motion is called projectile motion. The purpose of this lab is to study projectile motion and its properties. The experiment is done to measure the distance that the ball will travel when it is shot from the spring gun. For this purpose, we mounted a gun on the table and clamp it. We determine the vertical distance from the ground to the gun.

We found out that the distance was 1. We put paper at some horizontal distance from the table where the gun was leveled. We made sure all the screws and clamps were tight. We adjust the pointer so that it indicates 0 degree. Then we shot the plastic ball from the spring gun.

The ball hits the paper. We shot the ball ten times and we measure the distance between the spring gun and the paper. For the experiment we used spring gun but the basic setup of the experiment looks like the figure.

After the ball is fired then the ball is in motion. At that time the force acting on it is gravity mg where m is the mass of the ball and gravity is the horizontal force. So, we can write. There is no force acting on X-direction. So, the only force acting on it is vertical force.

To find the final distance it travelled, we used kinematic equations. For X-direction where there is no acceleration. The horizontal and vertical motion is independent of each other except that they have common time. So, the time that we calculate for horizontal motion is the same for vertical motion and vice- versa.

We consider the vertical motion. Therefore, the equation becomes. Now, using t for horizontal motion.

### Lab 3 : Projectile Motion

For distance, we shot the ball ten times. We calculated the distance for ten shots and found the following results:. Distance m. To find out the average horizontal distance range we took the average from the ten results. We adjust the pointer so that it indicates 30 degree. We repeat the same procedure.

The basic setup for the diagram looks like the figure. Considering the freefall diagram for ball at any point in projectile motion. Velocity of the ball can be splitted into two parts. Hence using quadratic equation formula.

Comparing the equation obtained for t with x we get.Once you have collected your data and analysed it, you can begin to compile your report. Weight is the.

### Projectile Motion Lab Report Paper

In order to record the timing from the photogates, a computer software was used to record the times and speed velocity. Based on previous knowledge learned during several lectures towards two-dimensional kinematics, various assumptions were made about predicting where the ball was going to hit the target. Theory: In physics, a projectile is an object that has initial velocity given as v 0.

Projectile is subjected only to gravity with an assumption that there is no air resistance force acting on the projectile. The assumption is only valid if the object is relatively small and the area of the object is small, which is the case in this experiment. The object will be in free fall in the vertical direction since gravity is the only force to be acting on the object after the initial velocity. The target was held down with tape in order for it to remain static. Also, photogates were placed within a short distance of each other towards the end of the ramp after the small ramp.

This was placed in such a way so that the ball would roll down the ramp, through the two photogates and make contact on the target. Photogate 1 was closely connected to the interface of Photogate 2. The first trials that were taken, the ball must be caught before it hits the ground and after it travels through the photogates. Many trials were conducted. However, before recording the data, we began to make various assumption of where the ball would make impact with the target.

We were able to make this prediction after the various measure of the ten trials we did before hitting the target. With the information of the velocity and time of the ball traveling down the ramp and through the photogates, we were able to make a precise and accurate assumption of where the ball would make impact with the target.
