Newton's 1st Law of Motion is __________.

• This law means an object at rest will stay at rest and an object in motion will stay in motion (at a constant speed and in a straight line), unless acted on by an outside force.

• For every action, there is an equal and opposite reaction.

• Newton's 2nd Law of Motion means the greater the mass of an object, the more force it will take to accelerate the object. (F = ma)

• There are no laws of motion from Newton.

Newton's 3rd Law of Motion is __________.

• This law means an object at rest will stay at rest and an object in motion will stay in motion (at a constant speed and in a straight line), unless acted on by an outside force.

• For every action, there is an equal and opposite reaction.

• Newton's 2nd Law of Motion means the greater the mass of an object, the more force it will take to accelerate the object. (F = ma)

• There are no laws of motion from Newton.

What is net force?

• The difference (all the forces subtracted together) of all of the forces acting on an object.

• The sum (all forces added together) of all of the forces acting on an object.

• The amount of force you use for a net.

• Gravity
