Unit 4 Review

Front

What is the definition of velocity?

Back

Velocity is the speed of an object 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

What is the formula for calculating average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

If a horse travels 20 meters in 5 seconds, what is its average speed?

Back

4 m/s.

Front

What is the SI unit for measuring speed?

Back

The SI unit for speed is meters per second (m/s).

Front

What does a flat line on a distance-time graph represent?

Back

A flat line on a distance-time graph indicates that the object is at rest and not moving.

Front

How do you interpret a distance-time graph with a steep slope?

Back

A steep slope on a distance-time graph indicates that the object is moving quickly.

Front

What is the scientific (SI) unit for measuring distance?

Back

The scientific (SI) unit for measuring distance is the meter.

Front

What does the term 'average speed' mean?

Back

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

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it determines the object's path and is essential for understanding motion.
