FLASHCARD QUESTION
Front
What is the relationship between mass and kinetic energy?
Back
Kinetic energy is directly proportional to the mass of the object. As mass increases, kinetic energy increases if velocity remains constant.

FLASHCARD QUESTION
Front
What is the relationship between velocity and kinetic energy?
Back
Kinetic energy is proportional to the square of the velocity. If velocity doubles, kinetic energy increases by a factor of four.
