Equations

Displacement

Displacement is a vector quantity. Distance is a scalar quantity.

Calculate the coaches distance traveled and displacement after he stops on point C.

Calculate displacement and distance

Displacement

Equations

Average Velocity

Speed is scalar. Velocity is vector

A car is traveling North on a road. If it is 50 m from one intersection to the next, and it takes the car 10 s to cover the distance between intersections, how fast is the car traveling?

​

Units for Velocity are m/s

​Average Velocity

Equations

Average Acceleration

Accelerations units are m/s^2

A cheetah runs at a steady velocity of 60 km/h (16.7 m/s). Over a period of 5.0 s, the cheetah increases its pace to 95 km/h (26.4 m/s). What is the average acceleration of the cheetah over this period?

​

Acceleration is a measure of change in velocity over time.
