Newton's Laws Review

What is Newton's 1st Law?

• An object in motion stays in motion, an object at rest stays at rest, unless acted on by an unbalanced force.

• Force = Mass x Acceleration

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

What is Newton's 2nd Law?

• An object in motion stays in motion, an object at rest stays at rest, unless acted on by an unbalanced force.

• Force = Mass x Acceleration

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

What is Newton's 3rd Law?

• An object in motion stays in motion, an object at rest stays at rest, unless acted on by an unbalanced force.

• Force = Mass x Acceleration

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

• weight

• applied force

• mass
