Unit 1 - Kinetic and Potential Energy

potential energy

the energy that a body has by virtue of its position

kinetic energy

the energy that a body has by virtue of its motion

velocity

the speed and direction of a moving object

acceleration

when the velocity of an object changes; slows down or speeds up

force

a push or pull on an object

friction

a force that opposes motion between two surfaces that are touching; slows down

gravitational potential energy

energy stored that depends on the height of the object

elastic potential energy

energy stored by something that can stretch or compress

chemical potential energy

energy stored in a substance because of its composition

work

when a force causes an object to move in the direction of the force
