Distinguish between speed and velocity.
Distinguish between speed and velocity.
Open in App
Solution
Speed
- Speed is measured as the ratio of distance covered to the time taken to cover.
- It is a scalar quantity as it has only direction and no magnitude.
Velocity
- The velocity of an object can be defined as the rate of change of the displacement of the object from its initial position with respect to time.
- It might sound complicated but velocity is basically speeding in a specific direction.
- It is a vector quantity.
Difference between speed and velocity
Speed Velocity The rate at which an object covers a certain distance is known as speed. The rate at which an object changes position in a certain direction. Speed cannot be negative or zero. It can be negative or zero. Speed is a scalar quantity. It is a vector quantity. Example:
A man making a roundabout journey at a speed of 40 kmph. Example:
A woman plans to drive her vehicle at a speed of 76 kmph towards East.
