Speed and Velocity

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is velocity?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a car travels 120 kilometers in 2 hours, what is its speed?

Back

60 km/h.

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 acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

If a runner increases their speed from 5 m/s to 10 m/s in 2 seconds, what is their acceleration?

Back

2.5 m/s².

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only, such as speed.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity.

Front

How do you calculate average speed?

Back

Average Speed = Total Distance / Total Time.
