Momentum and Impulse

Question 1

Momentum

Answer 1

Momentum is the product of an object’s mass and its velocity.
p=mv

Question 2

Linear Momentum

Answer 2

Linear Momentum is a vector quantity with the same direction as the velocity of the object.

Question 3

Newton’s second law of motion in terms of momentum

Answer 3

Newton’s second law of motion in terms of momentum states that 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

Impulse

Answer 4

Impulse is the product of the resultant/net force acting on an object and the time the net force acts on the object.
Fnet△t=m△v

Question 5

The Principle of Conservation of Linear Momentum

Answer 5

The principle of conservation of linear momentum states that the total linear momentum of
an isolated system remains constant (is conserved).

Question 6

Explain Elastic Collision

Answer 6

An Elastic Collision is a collision in which both the total momentum and total kinetic energy are conserved.

Question 7

Explain Isolated System

Answer 7

An Isolated System is a system on which the resultant/net external force is zero.
