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) or kilometers per hour (km/h).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, such as 10 m/s north.

Front

What is the formula for calculating speed?

Back

Speed = distance / time.

Front

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

Back

Speed = 100 m / 5 s = 20 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

If Aiden's car travels at 25 m/s and Abigail's at 10 m/s, which car is faster?

Back

Aiden's car at 25 m/s is faster.

Front

What does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time.

Front

What is an example of velocity?

Back

A car moving at 60 km/h east.

Front

If a toy car moves 15 meters in 3 seconds, what is its speed?

Back

Speed = 15 m / 3 s = 5 m/s.

Front

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

Back

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