Speed and Velocity

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is the definition of velocity?

Back

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

Front

How do you calculate average speed?

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 that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

If a car travels 120 kilometers in 2 hours, what is its average speed?

Back

The average speed is 60 km/h.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time.

Front

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

Back

It means the object is moving at a constant speed in a straight line without changing direction.

Front

What is instantaneous speed?

Back

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

Front

How can you determine if an object is accelerating?

Back

An object is accelerating if its velocity is changing, which can be due to a change in speed or direction.

Front

What is the unit of measurement for velocity?

Back

The unit of measurement for velocity is typically meters per second (m/s) with a direction.
