Differentiating Speed, Velocity, Distance, and Displacement

What type of quantity is speed?

• Scalar

• Vector

• Neither

• Both

Which of the following is an example of velocity?

• A person running at 4 meters per second

• A plane flying at 250 meters per second

• A car moving at 60 km/h

• A train traveling backwards at 55 meters per second

What is the main difference between distance and displacement?

• Neither have direction

• Both have direction

• Displacement has direction, distance does not

• Distance has direction, displacement does not

How do you calculate the speed of an object?

• Divide distance by time

• Multiply distance by time

• Subtract time from distance

• Add distance and time

If a train travels 550 meters east in 10 seconds, what is its velocity?

• 55 meters per second

• 550 meters per second east

• 550 meters per second

• 55 meters per second east
