Match the following physics concepts with their definitions:

Newton's First Law = An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Kinetic Energy = The energy an object possesses due to its motion. Acceleration = The rate of change of velocity of an object with respect to time. Work = The measure of energy transfer that occurs when an object is moved over a distance by an external force. Signup and view all the answers
