Distance, Displacement, Speed, and Velocity

Front

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 like velocity but without a direction

Back

Speed is like velocity but without a direction

Front

What is a difference between distance and displacement?

Back

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