Understanding Displacement and Velocity

What is the displacement if you walk 30 meters straight and then 40 meters to the left?

• 30 meters

• 70 meters

• 50 meters

• 40 meters

Which of the following is a vector quantity?

• Time

• Displacement

• Speed

• Distance

Why is the displacement zero when you return to your starting point?

• Because displacement is always zero

• Because displacement only considers the path traveled

• Because the starting and ending points are the same

• Because the total distance traveled is zero

How is speed different from velocity?

• Speed includes direction, velocity does not

• Speed is a vector quantity, velocity is scalar

• Speed is always greater than velocity

• Speed is scalar, velocity includes direction

If it takes 100 seconds to reach the market, what is the velocity if the displacement is 50 meters?

• 1.0 m/s

• 0.3 m/s

• 0.5 m/s

• 0.7 m/s
