Newton's First Law:

• Force = Mass times Acceleration

• If an object has more mass, more force needs to be applied to it

• An object will remain at rest, until another force causes it to move

• For every action there is an equal and opposite reaction

What is the tendency of an object to resist a change in motion?

• coffee

• motion

• inertia

• gravity
