What is speed?

Back

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

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the unit of speed?

Back

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

Front

What does it mean if an object is stationary?

Back

An object is stationary if it is not moving and its speed is 0 m/s.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is a head start in a race?

Back

A head start is when one runner begins the race ahead of the others, giving them an advantage.

Front

If a runner completes a 100 meter dash in 10 seconds, what is their average speed?

Back

10 m/s (calculated as 100 meters / 10 seconds).

Front

If a runner takes 100 seconds to run 10 meters, what is their speed?

Back

0.1 m/s (calculated as 10 meters / 100 seconds).

Front

What does it mean to run at a steady speed?

Back

Running at a steady speed means maintaining a constant speed without speeding up or slowing down.

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.
