Energy Problems

Use these physics problems to test your knowledge on many different energy problems.

Semicircles

This problem set explores the momentum and energy present in balls travelling through semicircles and their relations to the semicircle’s radius.

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:

Ball on a Moving Cart

The trajectory of a ball dropped from a person on a moving cart will be modelled using both x-position vs. time graphs and y-position vs. time graphs. The scenario will be analyzed from the point of view of an observer on the cart and on the ground.

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.
