Speed Velocity and Acceleration Practice

Front

What is Speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity and does not include direction.

Front

What is Velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What is a Reference Point?

Back

A reference point is a stationary object used to determine the position of another object.

Front

How do you calculate Speed?

Back

Speed = Distance / 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 an example of positive acceleration?

Back

A car speeding up from 20 m/s to 40 m/s is an example of positive acceleration.

Front

What is an example of negative acceleration?

Back

A car slowing down from 60 m/s to 30 m/s is an example of negative acceleration.

Front

If a runner completes a 400m lap in 50 seconds, what is their speed?

Back

Speed = 400m / 50s = 8 m/s.

Front

What happens to the velocity of an object if it is at rest?

Back

If an object is at rest, its velocity is 0 m/s.
