Launching+Distance

By Dennis and Nathaniel

Launch Force and Mass Goal: How would the mass of the car and launch force affects its stopping distance?

1st Procedure: Different Mass 1. Find the mass of the car 2.Set up the stage by placing 2 weights at one side of the ramp opposite of each other and wrap a rubber band from one to another. 3. Use the force scale to find the amount of force there is on the rubber when being pulled on. 4.Use average force on the car for each trial 5. For each trial use different masses on the car 6. Use meter stick to find the car's stopping distance.

Data: Different Masses Mass of the car: 256 gram

__Force l Mass l Distance__ 2N 256g 57cm 2N 506g 34cm 2N 756g 22cm 2N 1006g 17cm

Data Analysis: In this graph we can see as the mass of the car increases, the distance it travels decreases.

2nd Procedure: 1.Follow the same procedure 1 to 3 from the 1st procedure 2.use constant mass of the car 3. For each trial, use different force

Data: Using Different launch force and same mass. Mass of the car : 256gram

__Force l Mass l Distance__ 2N 256g 34cm 3N 256g 76cm 4N 256g 106 cm 5N 256g 193cm Data Analysis: In this graph, one can see that as the launch force increases, the distance of the car decreases

3rd Procedure: 1. Follow procedure 1 to 3 from the 1st procedure 2. For each trial, different mass and force

Data: Different Mass and launch force.

1st __Force l Mass l Distance__ 3N 506g 47cm 3N 756g 31cm 3N 1006g 23cm

2nd __Force l Mass l Distance__ 4N 506g 55cm 4N 756g 49cm 4N 1006g 36cm

3rd __Force l Mass l Distance__ 5N 506g 70cm 5N 756g 57cm 5N 1006g 40 cm

Data Analysis; The third procedure is a combination of the 1st and 2nd procedure where the force is changed as well as the mass of the cart to determine the distance travelled by the cart.

Conclusion: By doing this lab, my partner and i were able to find the relation ship between mass and launch force and how it will affect a car's distance. 1st part of the lab, we used different masses for the car and the same launch force and we found that as the mass of the car increase, the distance it travels decreases.For the 2nd part of the lab, we used different launch forces with the same mass of the car and we were able to found that as the launch force increases, the stopping distance of the car increases. For third part of the lab we discovered that the ideas that we got from the first and second procedure, were applicable in many different situations. Doing this lab taught us that the relation between launch force and mass was inverse. In everyday life, i always see this principle being applied in many activities. For example, when i was a kid i used to like playing with sling shot. While i was playing with it, i could see that as i used heavier rocks to sling, the distance it travels decreases. Doing this lab, it made me realize that physics is always in action in the real world.
