Momentum and Impulse

Question 1

What is Momentum?

Answer 1

> The product of an object’s
mass and its velocity.

Question 2

What is Linear Momentum?

Answer 2

> A vector quantity with the same direction as the velocity of the object.

Question 3

Describe Newton 2 in terms of Momentum.

Answer 3

> The Net (or resultant) force acting on an object is equal to the Rate of Change of Momentum of the object in the Direction of the net force.

> Fnet=^p / ^t

Question 4

What is Impulse?

Answer 4

> The product of the resultant/net force acting on an object and the time the net force acts on the object.

Question 5

What is an Elastic collision?

Answer 5

> A collision in which there is no net loss in kinetic energy in the system as a result of the collision.

Question 6

What is an Inelastic Collision?

Answer 6

> A collision in which there is a loss of kinetic energy.

Question 7

What is the Principle of Conservation of Linear Momentum?

Answer 7

> The total linear momentum of an isolated system remains constant.
