Momentum
What does momentum depend on?
Mass and velocity
What is displacement?
(multiple acceptable definitions)
The distance from your starting point
How is speed different from velocity?
Speed is distance over time.
Velocity is speed + direction
convert 300 mm to km
0.0003 km
What is density?
How compact something is
If two people are running towards each other
Person 1 weights 100 ibs and runs at 10 mph
Person 2 weights 200 ibs and runs at 5 mph
Who has more momentum?
Neither their momentum is the same
If I walk 30 meters north and then walk 50 meters south, what's the total distance I traveled?
80 meters?
If a car is driving at a constant speed in a circle. Is its acceleration changing?
Yes
Convert 5 kL to L
5,000 L
Mass is the amount of matter in an object. Volume is the amount of space something takes up
If a car weighs 4000 kg and is moving at 70 km/h
what is its momentum?
280,000 kg m/h
If I walk 20 miles north, then turn around and walk 20 miles south to where I started, what's my displacement?
0
What is centripetal acceleration/centripetal motion?
Acceleration in a circular motion (circle)
Convert 0.67 m to mm
670 mm
