Speed

Front

What is speed?

Back

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

Front

What is the formula to calculate speed?

Back

S = d/t, where S is speed, d is distance, and t is time.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s) or kilometers per hour (km/hr).

Front

What is the unit of distance?

Back

The unit of distance can be meters (m), kilometers (km), miles (mi), etc.

If a car travels 100 kilometers in 2 hours, what is its average speed?

Back

Average speed = distance/time = 100 km / 2 hr = 50 km/hr.

Front

What is the average speed of a jogger who runs 400 meters in 267 seconds?

Back

Average speed = distance/time = 400 m / 267 s ≈ 1.5 m/s.

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 a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction, such as speed or mass.

Front

What is a vector quantity?

Back

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

Front

What is the average speed of a person who jogs 800 meters in 400 seconds?

Back

Average speed = distance/time = 800 m / 400 s = 2 m/s.
