Force and Motion Study Cards

An object at rest stays at rest and an object in motion stays in motion at same direction and speed unless acted on by an unbalanced force

Acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force needed to accelerate the object

For every action there is an equal and opposite reaction
