Impulse, Momentum and Collisions. momentum = mass x velocity p = mv units: kgm/s or Ns.

Momentum Momentum is a measure of how hard it is to stop or turn a moving object. What characteristics of an object would make it hard to stop or turn?

1. How does the change in momentum compare between a quick stop (collision) and a controlled stop (braking) from the same velocity? Why?

Momentum & Impulse and Projectile Motion. Momentum What is momentum? It is the quantity of motion of a moving body, measured as a product of its mass.

Draw/Answer the following Problem

Today’s Vocabulary IMPULSE

IMPULSE

Impulse ( Change in Momentum) A 50 kg man is walking at a velocity of 3m/s. All of a sudden he starts running with a velocity of 10 m/s. What was the man’s initial momentum? What was the man’s final momentum? What was the man’s impulse?

Impulse ( Change in Momentum) M = 1 kg v = 2 m/s M = 1 kg v = -2 m/s

Impulse ( Force x Time) A 20 kg cart hits a brick wall with a force of 100 N. If it took the cart 5 seconds to hit the wall, what is the cart’s impulse?
