Momentum Notes (p 42)

What is momentum?

What is momentum?

What is momentum? Momentum is an indication of how hard it would be to stop the object. If you were running, you might have a mass of 50 kilograms and a velocity of 10 meters per second west. Your momentum would be 500 kg-m/sec west. Momentum is another vector measurement and is always in the same direction as velocity.

What is momentum? When you throw a ball at someone and it hits him hard, it hurts because it was difficult to stop (had momentum). If you throw a small ball and a large ball at the same speeds, the large ball will hit a person with a greater momentum, be harder to stop, and hurt more. When the mass is greater (at the same speeds), the momentum is greater.

Change in Momentum What would it take to change an objects momentum? The total change in an objects momentum is equal to the amount of force applied multiplied by the time it was applied for. Force!

Impulse – Momentum The force multiplied by the time is called the impulse. The mass multiplied by the change in velocity just the change in momentum.

Force x Time = Mass x ∆Velocity

More Momentum A bullet is an example of an object with a very small mass that has a lot of momentum because it is moving very quickly. Bullets are therefore difficult to stop; it's a good idea not to try!

Collisions! Momentum is extremely useful for examining what happens in a collision. There are two different types of collisions: elastic and inelastic

Collisions! In a collision, momentum is conserved. This means that the total amount of momentum in all the collisions stays the same.

Conservation of Momentum Newton’s 3rd Law Forces act for the same amount of time.

Conservation of Momentum

Elastic Collision Inelastic Collision The product of the total mass and the total velocity is conserved (it stays the same)!
