Collisions in 1 and 2 Dimensions |
In today's lab period you will:
1 Elasticity and Conservation of Kinetic Energy |
Go to the applet Collision 1D and open the lesson labeled Lesson 3: Elasticity and Conservation of Kinetic Energy. Use the applet to help answer all of the questions in the tutorial. It is a good idea to work on this with a partner but each person is expected to hand in their own worked tutorial.
2 Conservation of Momentum in 2D Collisions |
Go to the applet Collision 2D and open the lesson labeled Lesson 2: Conservation of Momentum in 2D Collisions. Use the applet to help answer all of the questions in the tutorial. It is a good idea to work on this with a partner but each person is expected to hand in their own worked tutorial.
3 Video Analysis of a 2D Collision |
Go to the following video lab link - vl_pool.html - and analyze the collision between the two pool balls. Each ball has a mass of 0.160 kg and a radius of 0.032 m. Prepare a data table in which you provide the following information:
Include as well, an Excel graph showing the trend lines that you used to determine the velocities of the balls. Write a paragraph in which you discuss whether or not your experiment shows that momentum was conserved and that the collision was highly elastic. Find the coefficient of restitution (use energy and/or relative velocity) and show your calculations.
