Speed and Velocity

Front

What are the two components that define velocity?

Back

Speed and direction.

Front

If an object travels at a speed of 15 m/s for 3 seconds, how do you calculate the distance traveled?

Back

Distance = speed × time = 15 m/s × 3 s = 45 m.

Front

What does the unit 'Km' (kilometers) measure?

Back

Distance.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to another object.

Front

What is an example of velocity?

Back

65 mi/hr South.

Front

How is speed defined in physics?

Back

Speed is the distance traveled per unit of 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 the formula for calculating average speed?

Back

Average speed = total distance / total time.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude and no direction (e.g., speed).

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction (e.g., velocity).
