Momentum Problems
Additional problems – Use these physics problems to test your knowledge on momentum and collisions. 
Jumping
The interaction of the earth with a jumping person is explained using the momentum principle.
Water Tanks
Energy conservation and introductory thermodynamics are explored using this simplified model of two colliding water tanks.
Bouncing Balls
Principles of momentum are used to explain what happens when two balls of perfect elasticity are dropped from a certain height.
Skateboard Physics
Concepts of kinetic and potential energy will be explored by analyzing the motion of a skateboarder on a curved track.
The questions are based off the following PhET simulation, which can be used to double check answers:

Two Block Collisions
How do two objects behave after they collide with one another? The role of momentum and energy in determining the outcome of collisions will be explored in the following set of questions.
Final Speeds
Energy conservation will be used to compare the final speeds of objects dropped from a variety of different initial states. Students must understand how gravitational potential energy converts into kinetic energy.
