Speed Velocity and Acceleration Practice

Front

What is speed?

Back

Speed is the distance traveled per unit of time, measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, measured in meters per second (m/s).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

Front

Which of the following is an example of speed? A dog running at 3 m/s, A migrating bird headed south for the winter at 3 m/s.

Back

A dog running at 3 m/s.

Front

Which of the following is an example of velocity? A deer sprinting at 4 m/s, A migrating bird headed south for the winter at 3 m/s.

Back

A migrating bird headed south for the winter at 3 m/s.

Front

What happens to the speed of an object when it accelerates?

Back

The speed of an object increases when it accelerates.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If an object is moving at a constant speed, what can be said about its acceleration?

Back

If an object is moving at a constant speed, its acceleration is zero.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is an example of negative acceleration?

Back

Slowing down is an example of negative acceleration.
