2

Momentum

  • Quantity of motion

  • p=mxv

  • Describe an instance where two objects can have the same momentum

3

Fill in the Blank

A 1200 kg car is driven through town with a speed of 15 m/s. What is the magnitude of the car's momentum?

4

Open Ended

A bean bag and ball are each 1 kg. both fall to the earth at 4 m/s. The beanbag stops, the ball bounces back up.Which will have the greater change in momentum? Why?

5

Momentum

  • The momentum in a system is a vector sum.

  • This means that multiple objects in a system can either increase or decrease the system.

6

Open Ended

Describe a system where multiple objects increase the momentum in a system.

7

Impulse

  • Described two ways

  • 1. Force acting for a time. I= F x t

  • 2.Impulse is change in momentum.

  •  I= ΔpI=\ \Delta p  

  •  Δp = FΔt\Delta p\ =\ F\Delta t  

  •  mΔv=FΔtm\Delta v=F\Delta t  

8

Fill in the Blank

A force acts on a bicycle for 12 s and changes its momentum from 15 kg m/s in the positive x direction to 38 kg m/s in the positive x direction. What are the magnitude and the direction of the force?

9

Fill in the Blank

An impulse of 12.2 kg m/s is delivered to an object whose initical momentum is 4.5 kg m/s. The impulse has the same direction as the initial momentum. What is the object's final momentum?
