Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, regardless of direction.

Front

What is the definition of velocity?

Back

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

Front

What two factors does velocity depend on?

Back

Front

What two factors does speed depend on?

Back

Speed depends on distance and time.

Front

How is average speed calculated?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

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).

If a car travels 100 km north in 2 hours, what is its velocity?

Back

The velocity is 50 km/h north.

Front

What is instantaneous speed?

Back

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

Front

What is acceleration?

Back

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