Distance, and velocity

Front

What is displacement?

Back

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

Front

Displacement is distance combined with what?

Back

Direction.

What does velocity measure?

Back

Velocity measures the rate of change of displacement with respect to time, including direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes direction.

Front

What is the formula for calculating average speed?

Back
