Forces & Motion

What is the definition of acceleration?

• A change in velocity over time

• The ability to do work

• A force between surfaces

• The speed and direction of an object

What is a force?

• A change in an object’s position

• Any push or pull

• The tendency of an object to stay at rest

• The movement of energy from one object to another
