Speed and Velocity

Front

What is the definition of speed?

Back

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

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is the average speed of an object?

Back

Average speed is the total distance traveled divided 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

What is the formula for calculating velocity?

Back

Velocity is calculated by dividing displacement by time (Velocity = Displacement / Time).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

If a car travels 100 meters north in 5 seconds, what is its velocity?

Back

The velocity is 20 m/s north.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction, such as speed.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity.

Front

How does acceleration relate to speed and velocity?

Back

Acceleration is the rate of change of velocity over time, which can involve changes in speed, direction, or both.
