Distance, Displacement, Speed, and Velocity

What is a difference between distance and displacement

• Distance is measured in seconds and displacement is measured in meters

• Distance is always shorter than displacement

• Displacement can be equal to zero if the object ends in the place it began in

• Distance can be equal to infinite when only a small distance has been travelled

• 0.625 m

• 100,000 m

• 1.6 m

• 650 m

A horse follows a dangling carrot for 20 m, if it took her 50 seconds to reach it, what was her average velocity?

• 0.4 m/s

• 20 m/s

How many seconds does it take to travel 800 m at a speed of 25 m/s?

• 32 s

• 20,000 s

• 0.03 s

• 25 s
