Calculating Speed

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 speed?

Back

Speed is the measure of how much distance is covered over a period of time.

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

Front

How do you calculate speed using distance and time?

Back

Speed is calculated by dividing the distance traveled by the time taken (S = d/t).

Front

What is the unit of speed in the metric system?

Back

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

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

The speed is 20 meters per second (100 m / 5 s = 20 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 average speed?

Back

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

Front

If a runner completes a 400-meter lap in 50 seconds, what is their average speed?

Back

The average speed is 8 meters per second (400 m / 50 s = 8 m/s).

Front

What is instantaneous speed?

Back

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