Difference Between Speed And Velocity

1. Define Speed.

Speed of the body is the ratio of the distance to time. It is the rate of change in distance with respect to time. 

2. When would you use speed instead of velocity?

Speed is used when we want to know how fast an object is moving, irrespective of the direction.

3. Define Velocity. 

 Velocity of the body is the ratio of the displacement to time. It is the rate of change in displacement with respect to time.

4. Can you have negative velocity?

Yes, negative velocity means you are moving in the opposite direction. For example, if your velocity is -30 m/s to the east, it means you are moving west at 30 meters per second.

5. Do speed and velocity have the same units?

Yes, speed and velocity are both measured in meters per second (m/s) or kilometers per hour (km/h).

6. State the formula of Speed.

 Formula for speed is given by:  Speed = Distance / Time

7. State the Formula of Velocity.

Formula for velocity is given by: Velocity = Displacement / Time

This article is about the difference between speed and velocity. Speed is the rate of change of distance according to time. It is scalar quantity i.e. speed has magnitude but no direction. Velocity is the rate of change of displacement according to time. It is vector quantity i.e. velocity has both magnitude and direction. Speed is the ratio of distance to time and velocity is the ratio of displacement to time. Speed magnitude is a non-zero positive number while velocity magnitude can be positive, negative, or zero.
