What is velocity?
Think about what distinguishes speed from velocity.
True or False: Velocity can be negative.
Remember the directions you have studied.
A runner completes a lap of a circular track with a radius of 50 meters in 60 seconds. Calculate the velocity if they start and end at the same point.
Consider the displacement before calculating.
A car travels 150 meters to the east, then 100 meters to the west in 20 seconds. Find the average velocity.
Use the displacement and divide by total time.
