Question
Displacement is a _________ quantity
- Scalar
- Vector
- Tensor
- Time
Hint:
Displacement has both magnitude and direction.
The correct answer is: Vector
- 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 which 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.
- Displacement is a vector quantity because it has both magnitude and direction.
