Speed, Velocity and Acceleration

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 per unit of time. It can be positive (speeding up) or negative (slowing down).

Front

How do you calculate Speed?

Back

Speed = Distance / Time.

Front

How do you calculate Velocity?

Back

Velocity = Displacement / 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 constant speed?

Back

A car traveling at 60 km/h on a straight road.

Front

What is an example of acceleration?

Back

A bicycle speeding up as it goes downhill.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is the unit of Speed?

Back

The unit of speed is typically meters per second (m/s) or kilometers per hour (km/h).
