Chapter 2: Laws of Motion

What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

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

The force of gravity on an object

• mass
• weight
• volume
• inertia

How does friction affect speed?

• more friction decreases speed
• more friction increases speed
• less friction decreases speed
• less friction doesn't affect speed

What is the force that acts between objects even though the objects are not touching

• Non-contact force
• Contact force
• Elemental force
• Invisible force

What does the force of gravity depend on?
