Speed and Velocity

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 velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

If a car travels 400 meters in 20 seconds, what is its speed?

Back

Speed = 400 meters / 20 seconds = 20 m/s.

Front

What is the total distance traveled if a cyclist moves 30 meters north and then 40 meters east?

Back

Total distance = 30 meters + 40 meters = 70 meters.

Front

What unit is used to measure speed?

Back

Speed is commonly measured in meters per second (m/s) or miles per hour (mph).

Front

Which of the following represents a velocity: 40 m or 40 m/s north?

Back

40 m/s north represents a velocity because it includes direction.

Front

What is average speed?

Back

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