Front

What is speed?

Back

A measurement of how fast an object is moving.

Front

How is speed calculated?

Back

Speed = Distance / Time

Front

What is the definition of velocity?

Back

The speed of an object in a particular direction.

Front

Back

The vehicle was traveling at a constant speed.

Front

What causes a change in velocity?

Back

A change in direction or speed.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

How is acceleration calculated?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

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 a vector?

Back

A quantity that has both magnitude and direction.

Front

What is a scalar?

Back

A quantity that has only magnitude and no direction.
