Flashcards
What is energy?
What is energy?
Energy is the ability to do work or cause change.
What is work in physics?
What is work in physics?
Work is done when a force causes an object to move a certain distance.
What is kinetic energy?
What is kinetic energy?
Kinetic energy is the energy of motion. The faster an object moves, the more kinetic energy it has. It depends on mass and speed.
What is potential energy?
What is potential energy?
Potential energy is stored energy due to an object's position or state. It depends on mass and height.
