Momentum and Impulse 3/24/15

Free fall equations ● Final velocity=acceleration*time ● Final distance= 1/2 * acceleration*(time^2)

Gravity practice ● If a man falls out of a plane and falls for 5 seconds what is his final position? ● Remember g=9.81m/s^2

Gravity problem ● For the same man what is his final velocity?

Gravity and free fall ● What could help lower this man’s velocity as he is travelling downwards?

Momentum ● the quantity of motion of a moving body ● We measure this as p(momentum)=m(mass)*v(velocity)

Momentum ● What do you think momentum means? ● Where can you see momentum in your daily life?

Units of momentum ● If we multiply mass and velocity what do you think the units of momentum will be?

Units of momentum ● The units of momentum are kg*m/s

Impulse ● The force applied to an object over time. ● J=F*(T2-T1)

Impulse ● Egg drop interactive

Conservation of momentum ● The amount of momentum in a system will always be the same unless acted upon by an outside force.

Conservation of momentum ● When two objects collide their momentum at the beginning will be the same after the collision

Car at a stop light ● Think of a car at a stop light. If a car comes from behind and hits it what happens?

Physics be hind the car crash ● Momentum of both cars before ● Momentum of cars after

Group Problem ● In groups solve the question on the back board
