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 the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, measured in meters per second (m/s).

Front

How do speed and velocity differ?

Back

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

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

Front

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

Back

Meters per second (m/s).

Front

What is average speed?

Back

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

Front

If a car travels 150 km in 3 hours, what is its average speed?

Back

Average speed = 150 km / 3 hours = 50 km/h.

Front

What is instantaneous speed?

Back

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

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity as it indicates the path along which an object is moving.
