Chapter 10.4 Momentum

Question 1

What is the equation of the momentum of a moving object?

Answer 1

Momentum, p(kgm/s)= mass, m(kg) X velocity, v (m/s)

Question 2

What is the definition of momentum?

Answer 2

Momentum can be defined as “mass in motion.” Momentum depends upon the variables mass and velocity.

Question 3

What is the definition of a closed system?

Answer 3

A closed system is a system in which the total momentum before and event is the same as the total momentum after an event. This is called conservation of momentum.

Question 4

What does the law of conservation of momentum state?

Answer 4

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Question 5

What can you use the law of conservation of momentum to predict?

Answer 5

You can use this to predict what happens whenever objects collide or push each other apart in an ‘explosion’.
