Speed and Velocity

Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity and does not include direction.

Front

What is velocity?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What unit is commonly used to measure speed?

Back

Meters per second (m/s) is commonly used to measure speed.

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 a car travels 100 km in 2 hours, what is its average speed?

Back

Average speed = 100 km / 2 hours = 50 km/h.

Front

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

Back

It means the object is traveling the same distance in equal intervals of time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).
