When an object is not moving because the forces acting on it are equal. (think of when we pushed on a student's shoulders and the student didn't move, do to the forces being equal)
What is a balanced force?

When the forces acting on an obejcet are not equal and the object moves.
What is an unbalanced force?
200
This is the transfer of heat from one object to another.
What is heat energy transfer?

Describe what happens to molecules when they change from a solid to a liquid.
What is speeding up and moving more freely?

Name evidence that proves a ball dropped from a greater height has more potential energy. A) kinetic energy increases as the ball bounces B) The ball at rest is potential C) The greater the distance between the ball and the floor, the greater the potential energy.
What is C, The greater the distance between the ball and the floor, the greater the potential energy.
