Speed, Acceleration and Velocity

Front

What is a reference point?

Back

An object that appears to stay in place and helps you detect motion in another object.

Front

What is the formula for calculating speed?

Back

Speed = distance / time.

Front

What is velocity?

Back

The speed of an object in a particular direction.

Front

How is velocity calculated?

Back

Velocity = Speed + direction.

Front

What does constant speed mean?

Back

An object is moving at the same speed over time.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is deceleration?

Back

A decrease in speed or negative acceleration.

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 average speed?

Back

Total distance traveled divided by the total time taken.

Front

What is instantaneous speed?

Back

The speed of an object at a specific moment in time.
