Speed, Acceleration and Velocity

Front

What is average speed?

Back

Total distance traveled divided by total time taken to travel that distance.

Front

What is motion?

Back

When an object changes its position compared to a reference point.

Front

What is velocity?

Back

Speed of an object in a particular direction.

Front

What is positive acceleration?

Back

An increase in speed over time, as seen when a runner speeds up from 9 mph to 9.8 mph.

Front

What is the formula for speed?

Back

Speed = Distance / Time.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

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 reference point?

Back

A stationary object used to determine the position of another object.

Front

What is negative acceleration?

Back

A decrease in speed over time.

Front

What is instantaneous speed?

Back

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