What is the definition of velocity?

Back

Velocity is speed in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

If a runner completes a 100 meter dash in 10 seconds, what is her average speed?

Back

10 m/s

Front

What units are commonly used to measure speed?

Back

Meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).

Front

How does acceleration relate to speed and velocity?

Back

Acceleration is the rate of change of velocity over time, which can involve changes in speed, direction, or both.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity because it determines the object's path and can affect the overall motion.

Front

Can an object have a constant speed but changing velocity?

Back

Yes, if the object is changing direction while maintaining the same speed, its velocity is changing.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.
