Speed, Velocity and Acceleration

Front

What is Speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity, meaning it has only magnitude and no direction.

Front

What is Velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is Acceleration?

Back

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

Front

How is Speed calculated?

Back

Speed = Distance / Time.

Front

How is Velocity calculated?

Back

Velocity = Displacement / Time.

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 (only magnitude), while Velocity is a vector quantity (magnitude and direction).

Front

What does a constant speed indicate?

Back

A constant speed indicates that an object is moving the same distance in equal intervals of time.

Front

What does a change in velocity indicate?

Back

A change in velocity indicates that an object is accelerating or decelerating.

Front

What is an example of positive acceleration?

Back

A car speeding up from 20 km/h to 60 km/h is an example of positive acceleration.
