Lab Setup (ALL LABS)
- In this photo on the right would be
- motion sensor as labeled instead
- of the force sensor
- that is actually pictured.
- There would also be an
- additional cart on the ramp
- completing the experiments.
Explosion
Two carts are touching and then they explode when a button is pressed on the top releasing the plastic bars.
Two carts are touching and then they explode when a button is pressed on the top releasing the plastic bars.
Calculations
initial momentum : 0
final momentum : 0.501 * -.15 + 0.501 * .15 = 0
% difference = 0
Conclusion
For this experiment the carts started connected and then separated from each other in different directions. From the explosion the carts had the same velocity other then one being positive and the other being negative. this showed the change in momentum as zero which proves that momentum was conserved.
Bouncy Collision (One Cart Moving)
Two Carts on a ramp, one cart is stationary while the other moves towards the cart then both bounce off each other.
initial momentum : 0
final momentum : 0.501 * -.15 + 0.501 * .15 = 0
% difference = 0

Bouncy Collision (One Cart Moving)
Two Carts on a ramp, one cart is stationary while the other moves towards the cart then both bounce off each other.
Calculations
initial momentum : 0.501 * 0.3 = 0.1503
final momentum : 0.501 * 0.3 = 0.1503
% difference : |.1503-.1503|/.1503 = 0%
Conclusion
In this experiment when the moving cart ran into the stationary cart it caused both carts to then move away from each other.
When they bounced apart the carts then moved in opposite directions at the same velocity. From recording this data and then finding that the change in momentum is 0 it can be concluded that momentum was conserved.
Bouncy Collision (Both Carts Moving)
Two Carts on a ramp, both carts move towards each other and then bounce off each other.
initial momentum : 0.501 * 0.3 = 0.1503
final momentum : 0.501 * 0.3 = 0.1503
% difference : |.1503-.1503|/.1503 = 0%

Bouncy Collision (Both Carts Moving)
Two Carts on a ramp, both carts move towards each other and then bounce off each other.
Calculations
initial momentum : 0.501 * 0.2 + 0.501 * -0.22 = -.01002
final momentum : 0.501 * 0.12 + 0.501 * -0.16 = -.02004
% difference : |-.02004+.01002|/.01002 = 50%
Conclusion
From this lab we were supposed to be able to prove the equation and conservation of momentum. In this experiment however my data did not exactly line up. From conducting the experiment I was able to conclude that it should have ended with a smaller percent difference. My precent difference was quite large and I would need to run the experiment again to actually prove the equation.
Sticky Collision (One Cart Moving)
Two Carts on a ramp, one cart moves towards the other and then they collide and stick together.
initial momentum : 0.501 * 0.2 + 0.501 * -0.22 = -.01002
final momentum : 0.501 * 0.12 + 0.501 * -0.16 = -.02004

Sticky Collision (One Cart Moving)
Two Carts on a ramp, one cart moves towards the other and then they collide and stick together.
Calculations
initial momentum : 0.501 * 0.64 = .32064
final momentum : 0.501 + 0.501 * 0.32 = .32064
% difference : |.32064-.32064|/.32064 = 0%
Conclusion
In this lab it originally started with one cart moving with one velocity and eventually transferred to both carts being stuck together and moving with the same velocity. From this the calculated percent difference is actually zero which proves the equation and the conservation of energy through the lab.

Sticky Collision (Both Carts Moving)
Two Carts on a ramp, both carts move towards each other and then they collide and stick together.
Calculations
initial momentum : .501 * .59 + .501 * -.53 = .03006
final momentum : .501 + .501 * -.04 = -.04008
% difference : |-.04008-.03006|/.03006 = 175%
Conclusion
In this lab we were supposed to verify the equations and show the conservation of momentum. While from doing the experiment I was able to conclude that my percent difference should be very small. My data however did not reflect my hypothesis. Due to my large difference I can not verify or
prove anything while I may believe that it should be a certain way I would have to conduct the experiment again to get accurate results.
Uncertainties
In these labs there were many possibilities for error and uncertainty. On root of this was the ramp was not exactly flat and even on both sides. Even though we attempted to fix the problem by placing paper underneath one side this was not a complete perfect fix. Another cause could have been the sensors when they recorded and when the stopped relating to the movement of the carts. Any of these issues could have caused problems in our data.
