Calculate the percent difference in magnitude of the momentum of Table To determine velocity of ball bearing in barrel of missile launcher: Therefore, the total change in momentum of this two-particle system is zero.
Times for overall journey: Look at the last columns of Table To determine velocity of combined body after collision: Below is our data for Part A. Examining the data for trial one, what do you conclude about the collision? Recorded measurements NOT including uncertainty: We attached 4 cm of opposite sides of Velcro tape to the smooth ends of the two carts.
We quickly cut the rubber band compressing the spring, holding the button on the timer so it recorded as we did so. Work out the theoretical velocity of the ball bearing in the barrel of the launcher.
Next, we moved the spring scale to the other side, and attached the tape to the cart without the spring.
This experiment proved my hypothesis correct. The muzzle velocity of this ball bearing gun is: What can you conclude about the conservation of momentum and the exploding spring?
Examining the date for trial two, what do you conclude about the collision? Leaving the carts and weight in place otherwise, we recompressed the spring with the same force as before. We taped 60 grams into each cart, before attaching approximately 75 cm of recording tape to the bottom of one of the carts.
Our data is below. We removed the rubber bumper from one of our carts, and put the spring, and two washers in its place. We needed to repeat this several times to get accurate results.
If so, what happens to the momentum when a car stops at a stop light? We measured and recorded the mass of each cart. We used the spring scale to measure both the cart with the spring and stopper, and the one without. The rest of the lab was relating to the conservation of momentum.
Is momentum conserved in both trials? From this exercise I learnt new method and techniques used in calculating errors and uncertainty. To determine mass of combined body after collision: We taped grams into the cart with the spring, and taped 60 grams into the other cart.
Therefore when the two bodies collide, they will exert forces on each other, equal in magnitude but opposite in direction. We put the other cart the one without the tape between 30 and 40 cm in front of the first cart, with Velcro ends facing each other.
We placed the cart without the spring on top of the tape, with its smooth end pressed against the spring. We threaded the other end of the tape through the recording timer.
Throughout the entire experiment the overall change in momentum equaled zero. During this lab I learned about how momentum can be used as one measure of motion. When the velocity slows, we would expect the cars mass to increase. This two-particle system is virtually isolated, thus the total change in momentum is zero.
Next, we measured from the end of the end of the bumper to the far side of the spring, and recorded it. We repeated the previous procedure, this time marking the tape after the collision.
When the two particles collided there momentum was conserved resulting in one body that was the combined mass and momentum of the previous bodies. We counted 6 spaces after this dot, and marked a second dot representing 0. Since this is impossible, it stops instead.
We taped grams into the first cart, and 60 grams in the second cart.Anti Essays offers essay examples to help students with their essay writing. Sign Up. Physics Conservation Of Momentum Essay.
