Momentum

Linear Momentum

• A vector quantity defined as the product of an object’s mass and velocity

• p = momentum

p = mass X velocity

Linear Momentum

•What does the term momentum mean to you?–What are examples of momentum?

Example 1

What velocity must a car with a mass of 1210 kg have in order to have a momentum of 5.6 X 104 kg·m/s to the east?

Example 2

An ostrich with a mass of 146 kg is running to the right with a velocity of 17 m/s. Find the momentum of the ostrich.

Example 3

A 21 kg child is riding a 5.9 kg bike with a velocity of 4.5 m/s to the north west.

What is the total momentum of the child and the bike together?

Example 4

A 21 kg child is riding a 5.9 kg bike with a velocity of 4.5 m/s to the north west.

What is the momentum of the child?

Example 5

A 21 kg child is riding a 5.9 kg bike with a velocity of 4.5 m/s to the north west.

What is the momentum of the bike?
