Flashcards
Kinetic Energy (KE)
Kinetic Energy (KE)
The energy an object possesses due to its motion. It depends on both the object's mass and velocity.
KE and Velocity
KE and Velocity
KE is directly proportional to the square of the velocity. Doubling velocity increases KE by a factor of four.
KE and Mass
KE and Mass
KE is directly proportional to mass. Doubling the mass doubles the KE.
