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 is the formula to calculate speed?

Back

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

Front

If an object travels 100 meters in 10 seconds, what is its speed?

Back

10 m/s.

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

How do you calculate average speed?

Back

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

Front

What is the unit of speed in the International System of Units (SI)?

Back

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

Front

If a car travels 150 kilometers north in 2 hours, what is its velocity?

Back

75 km/h north.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the formula for calculating velocity?

Back

Velocity = displacement / time.
