Unit 5 Review

Which of the following is a scalar quantity?

• Velocity

• Displacement

• Speed

• Acceleration

What is the difference between distance and displacement?

• Distance includes direction, displacement does not

• Displacement is always greater than distance

• Distance is a scalar quantity, while displacement is a vector quantity

• Distance and displacement are always equal

If a car moves 100 meters east and then 100 meters west, what is its displacement?

• 200 meters

• 100 meters

• 0 meters

• 50 meters

Speed is defined as:

• Distance traveled per unit time

• Change in displacement per unit time

• The rate of change of velocity

• The total distance traveled

A car travels at 20 m/s north for 5 seconds. What is its displacement?

Acceleration is defined as:

• The change in velocity over time

• The change in speed over distance

• The rate at which an object moves

• The distance covered per unit time

Which of the following scenarios represents acceleration?
