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

An evil ewok threw a rock with a force of 24.6N and an acceleration of 6m/s² at an innocent stormtrooper. What was the rocks mass?

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

Multiple Choice

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

What is an example of Newton's third law?

a car moving forward when being pushed forward

A ball rolling along a level surface will eventually slow down and stop

Jumping on a diving board

The resistance that one surface or an object encounters when moving against another

Multiple Choice

When a small car pushes a big truck, the truck applies an equal and opposite force on the car.

False

True

Multiple Choice

What happens to the balloon if the air is released ?

Balloon goes right

Balloon goes up

Balloon goes down
