Multiple Choice

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

Multiple Choice

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

Multiple Choice

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

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

Multiple Choice

An object in motion will stay in what kind of motion as long as the net forces acting on it are zero?

• slowing motion in a straight line
• accelerating motion in a straight line
• constant motion in a straight line
• constant motion in an unpredictable direction

Multiple Choice

One object has twice as much mass as another object. The first object also has also twice as much...

• velocity
• gracitational acceleration
• inertia
• all of these

Multiple Choice

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

Force = mass x acceleration

Multiple Choice

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

Multiple Choice

What is the equation for Newton's second law?

• Acceleration means a change in speed or direction of something
• Force equals mass times acceleration
• For every action, there is an equal and opposite reaction
• 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

Multiple Choice

Your car has a mass of 2500 kg and a force of 5000 N. How fast will it accelerate?

• 20 m/s²

• 2 m/s²

• 0.5 m/s²

• 120 N

Multiple Choice

• 4Kg

• 41kg

• 4.1kg

• 46kg

Multiple Choice

What happens when unbalanced forces act on an object at rest?

• the object remains at rest

• the object begins moving in an unpredictable direction

• the object begins moving in the direction of the net force

• the object begins moving opposite to the direction of net force

Multiple Choice

What is acceleration?

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

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
• Acceleration means a change in speed or direction of something
• For every action, there is an equal and opposite reaction
• Force equals mass times acceleration

Multiple Choice

What is velocity?

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

Multiple Choice
