Newton's 3rd law and momentum

Front

What is the definition of momentum?

Back

Momentum is defined as mass times velocity.

Front

What force propels a motor scooter along a highway?

Back

The force provided by the road.

Front

Which Newton's Law states that an object in motion tends to stay in that state of motion unless acted upon by an unbalanced force?

Back

This is a summary of Newton's First Law.

Front

If a red sports car is moving at 30 mph, how does its momentum compare to an identical blue sports car moving at 60 mph?

Back

The blue sports car has twice as much momentum as the red car.

Front

What happens to the velocity of two identical freight cars after a collision if one is at rest?

Back

The velocity of the combined cars after the collision is half as much as the first car before the collision.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What is the relationship between force and momentum?

Back

The change in momentum of an object is equal to the force applied multiplied by the time interval during which the force is applied.

Front

What is an example of Newton's First Law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops.

Front

How does mass affect momentum?

Back

An increase in mass will result in a proportional increase in momentum if velocity remains constant.
