What is kinetic energy?
Back
Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.
4.
FLASHCARD QUESTION
Front
How does potential energy convert to kinetic energy?
Back
Potential energy converts to kinetic energy when an object falls or moves downward, as its height decreases.
5.
FLASHCARD QUESTION
Front
What factors affect potential energy?
Back
Potential energy depends on the object's mass, height above the ground, and the gravitational force acting on it.
6.
FLASHCARD QUESTION
Front
What factors affect kinetic energy?
Back
Kinetic energy depends on the object's mass and its velocity; increasing either will increase kinetic energy.
