Back

Velocity is the speed of an object in a given direction.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

How do you calculate total distance?

Back

Total distance is the sum of all distances traveled, regardless of direction.

Front

How do you calculate displacement?

Back

Displacement is calculated as the final position minus the initial position.
