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?
