2/28 PotU: Momentum review and mousetrap car construction

Warm up

You don’t need to copy the question, just write down the information (with units) and show your calculation.

How much momentum does a 800 kg car moving at 2 m/s (about 5 MPH)? How about a 80 kg cyclist (and bike) riding at a 20 m/s (about 40 MPH)?

Record three things you learned this week. Each must be a complete sentence.

Answers:

• Car: 800 kg * 2 m/s = 1,600 kgm/s
• Cyclist: 80 kg * 20 m/s = 1,600 kgm/s

Class work

1. Complete the Momentum review/practice sheet and turn in.
