Speed and Velocity

Front

What is the formula to calculate speed?

Back

S = d/t

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is speed in a specific direction.

Front

What is the unit of speed?

Back

The unit of speed is typically meters per second (m/s) or kilometers per hour (km/h).

Front

If a car travels 100 kilometers in 2 hours, what is its speed?

Back

Speed = distance/time = 100 km / 2 hr = 50 km/hr.

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 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 acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

If a jogger runs 5 kilometers north in 30 minutes, what is their velocity?

Back

Velocity = 5 km north / 0.5 hr = 10 km/hr north.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude, such as speed.
