Newton's 1st Law states...

• An object at rest will remain at rest and an object in motion will remain in motion unless acted on by an outside force.

• F = ma

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

Newton's 2nd Law states...

• An object at rest will remain at rest and an object in motion will remain in motion unless acted on by an outside force.

• F = ma

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

Newton's 3rd Law states...

• An object at rest will remain at rest and an object in motion will remain in motion unless acted on by an outside force.

• F = ma

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

A baseball is thrown by an astronaut in deep space. There are no other forces or air resistance. What happens to the ball after leaving the astronaut's hand?

• It speeds up

• It slows down

• Its speed remains constant

• The ball starts to curve downward

What pulls with more gravitational force?

• The Earth pulling on you

• You pulling on the Earth

• Both forces are the same strength
