Force & Motion Test review

Which type of force(s) will cause a change in an object's motion?

• gravity
• zero net force
• balanced forces
• unbalanced forces

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

Newton's third law states that any action will have a(n) _______ and ______ reaction

• Equal and similar
• Equal and opposite
• Equal and different
• Greater and opposite

• first
• second
• third 
• fourth

What is Newton's Third Law?

• Object in motion stays in motion and an object at rest stays at rest unless acted on by a outside force
• Force = mass x acceleration
• For every action there is an equal and opposite reaction

• larger 
• smaller 
• equal
