What is inertia?

• The tendency to change motion

• The tendency to resist a change in motion

• The tendency to increase speed

• The tendency to decrease mass

What does Newton's first law state?

• Force is dependent upon mass and acceleration

• For every action there is an equal and opposite reaction

• An object in motion stays in motion until an unbalanced force acts on it

• Objects move in the direction of the greatest force
