Which is Newtons first law

• Force is equal to an objects mass times its velocity 
• an object in motion stays in motion or an object at rest stays at rest unless acted on by an outside force.
• Law of the land
• For every action there is an equal and opposite reaction

Which is Newtons third law

• Force is equal to an objects mass times its velocity 
• an object in motion stays in motion or an object at rest stays at rest unless acted on by an outside force.
• Law of inertia
• For every action there is an equal and opposite reaction
