Question

# Speed is a _________ quantity.

- Tensor
- Vector
- Scalar
- Universal

Hint:

### Scalar

## The correct answer is: Scalar

### Speed is a scaler quantity as it has no direction but only magnitude.

Speed is the rate of the change of distance with respect to time, while velocity is a vector quantity- it is the speed of an object in a particular direction.
