What is a reference point?

• A place or object that is staying still, that is used to determine if something else is moving.

• A place or spot where something is located

• The action of moving or being moved

• Shortest distance between starting position and ending position

Motion can be described through a change in _____.

• temperature

• distance

• position

• speed

20 km/hr is an example of

• direction

• speed

• distance

300 km/hr North is an example of

• One million miles

• 0

• two million miles

• none of the above

You are in a car going 20 km/h and another car passes you going in the opposite direction at 20 km/h. Do both cars have the same velocity?

• Yes, because they are both going 20 km/h
