Speed & Velocity

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or kilometers per hour (km/h).

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction, combining both magnitude and direction.

Front

What are the two components of velocity?

Back

Speed and direction.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

If an object travels 100 meters in 5 seconds, what is its speed?

Back

20 m/s.

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 is an example of velocity?

Back

A car moving at 60 km/h to the north.

Front

What happens to velocity if an object changes direction but maintains the same speed?

Back

The velocity changes because velocity depends on direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

If a cyclist speeds up from 10 km/h to 20 km/h, what type of acceleration is this?

Back

Positive acceleration.
