Distance, Displacement, Speed & Velocity Practice

Which is true?

• Speed is measured in m/s but velocity is measured in s/m

• Speed is a vector and velocity is a scalar

• Speed and velocity are the same exact thing

• Speed is a scalar quantity but velocity is a vector quantity

What is a difference between distance and displacement

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

• Distance is always shorter than displacement

• Distance is a measure of magnitude and displacement is a measure of magnitude and direction

• Distance is a vector quantity but displacement is a scalar quantity

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

• 32 s

• 20,000 s

• 0.03 s

• 25 s

• 2,250 m/s

• 0.9 m/s

• 1.1 m/s

• 95 m/s
