Newton's 1st & 2nd Law

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

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 

The tendency of an object to resist a change in its motion

• acceleration
• inertia
• mass
• frame of reference

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 2nd Law?

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

• Acceleration depends on two variables, the mass of the object and the amount of force.
