Speed and Velocity Calculations

Front

What is speed?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

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 unit is commonly used to measure speed?

Back

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

Front

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

Back

20 m/s.

Front

What information do you need to calculate speed?

Back

You need the distance traveled and the time taken to travel that distance.

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 200 meter race in 25 seconds, what is their average speed?

Back

8 m/s.

Front

What is instantaneous speed?

Back

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

Front

How does acceleration relate to speed?

Back

Acceleration is the rate of change of speed over time.
