Multiple Choice

Which of the following factors can increase the momentum of a moving object?

Increasing its mass

Decreasing its speed

Increasing its speed

Both increasing its mass and speed

Multiple Choice

Why is it harder to stop a large truck than a small car when both are moving at the same speed?

The truck has more speed

The truck has more mass

The car has less inertia

The car is smaller

Math Response

Type answer here

Deg^°

Rad

Multiple Select

What factors affect an object's momentum?

mass

acceleration

gravity

velocity

Multiple Choice

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

car

bike

they are equal

cannot determine using the info provided

Dropdown

Airbags and collapsible bumpers both

the

the force in a collision.

Multiple Choice

If the velocity of an object is tripled, how does its momentum change assuming mass remains constant?

It remains unchanged.

It doubles.

It triples.

It is halved.

Multiple Choice

What happens to the force of impact if the change in momentum occurs over a short period of time?

The force of impact is large

The force of impact is small

The force of impact does not change

The force of impact becomes zero

Multiple Choice

If you had to choose between hitting a haystack or a concrete wall in a car, which would you choose to decrease the force of impact, and why?

Haystack, because it increases the time of impact and reduces force.

Concrete wall, because it is stronger.

Haystack, because it decreases the time of impact.

Concrete wall, because it increases the force of impact.

Multiple Choice

Using the model from our notes,

What does our model say will happen with more force AND less time?

A change in Mass

A change in Velocity

A change in Newtons

Multiple Choice

Using the model from our notes,

If there's more time there's how much force?

More Force

Less Force

Some Force

Less Time

Multiple Choice

A boy kicks a football with a force of 20 N, the time the force acts for is 0.3 s. Calculate the impulse on the ball.

1 N⋅s

6 N⋅s

33.3 N⋅s

Multiple Choice

A 5 N force is applied to a 3 kg ball to slow it down from 9 m/s to 3 m/s. What is the impulse on the ball?

-2.5 N⋅s

-10 N⋅s

-18 N⋅s

-45 N⋅s

Multiple Choice

What is the main condition required for momentum to be conserved during collisions?

No external forces interfere

Objects must be at rest

Only one object is moving

The collision must be elastic

Multiple Choice

Which object listed below has the greatest momentum?

A 0.05 kg object rolling at 0.2 m/s.

A 0.15 kg object rolling at 2 m/s.

A 0.15 kg object rolling at 1 m/s

A 0.4 kg object rolling at 2 m/s.

Multiple Choice

A simple way to define momentum is

Mass in Motion

The size of an object

The velocity of an object

A comparison between two objects

Multiple Choice

The Law of Conservation of Momentum states:

The total momentum before a collision is equal to the total momentum after a collision.

The total momentum before a collision is greater than the total momentum after a collision.

The total momentum before a collision is less than the total momentum after a collision.

The total momentum before a collision is not related to the total momentum after a collision.
