• Newton's 3rd law is called action/reaction pairs

• Newtons 2nd law is called the law of inertia

• Newton's first law says an object in motion will stay in motion unless acted upon by a force

Fill in the Blanks

Force = mass x acceleration The bigger the mass the smaller the acceleration. The smaller the mass the

the acceleration.
