What does Newton's first law state?

• Acceleration means a change in speed or direction of something
• An object in motion tends to stay in motion while an object at rest tends to stay at rest unless acted on by some force
• Force equals mass times acceleration
• For every action, there is an equal and opposite reaction

What is inertia?

• A tendency to remain unchanged (keep moving or keep still)
• The resistance that one surface or an object encounters when moving against another
• The amount of stuff that makes up something
• A change in speed or direction of something

What is friction?

• A tendency to do nothing or to remain unchanged
• The amount of stuff that makes up something
• A change in speed or direction of something
• The resistance that one surface or an object encounters when moving against another

What is Newton's second law?

• For every action, there is an equal and opposite reaction
• Force equals mass times acceleration
• An object in motion tends to stay in motion while an object at rest tends to stay at rest unless acted on by some force
• Acceleration means a change in speed or direction of something

What type of force acts at a distance?

• Magnetism

• friction

• air resistance

What is Newton's third law?

• An object in motion tends to stay in motion while an object at rest tends to stay at rest unless acted on by some force

What is an example of Newton's first law?

• Trying to push a couch that's sitting on a fluffy rug is harder than pushing that same couch on a smooth floor
• Jumping on a diving board
• A pair of snow skis aren't going to go anywhere without a skier in them forcing them to move
• A ball rolling along a level surface will eventually slow down and stop due to friction

What is an example of inertia?

• Jumping on a diving board
• Trying to push a couch that's sitting on a fluffy rug is harder than pushing that same couch on a smooth floor
• A book on a table remaining at a rest
• A ball rolling along a level surface will eventually slow down and stop due to friction
