Question
Speed is a _____ quantity.
- Tensor
- Vector
- Scalar
- Random
Hint:
Speed has only magnitude, no direction.
The correct answer is: Scalar
- A scalar is some quantity which obeys simple algebraic rules, for example, addition, subtraction, etc. A scalar may also be defined as a quantity that requires only magnitude to be identified. e.g. temperature, current, etc.
- A vector is any quantity which doesn't follow algebraic rules. The addition or subtraction of vectors is not equal to the algebraic sum or difference of their magnitude. A vector may also be defined as a quantity that requires both direction and magnitude to be identified in space. e.g. velocity, force, etc.
- A tensor is a quantity which has different values when measured in different directions in space. e.g. moment of inertia.

Parallelogram law is used when _______
In parallelogram law of vector addition, it says that if we place two vectors so they have the same initial points(the tails are connected) and then complete the vectors into a parallelogram, then the sum of the vectors is directed diagonal that starts at the same point as the vectors.
