Question
Force has a ___ and a direction. Therefore, it is called a ___.
- Magnitude, scalar
- Magnitude, vector
- Scalar, magnitude
- Vector, magnitude
Hint:
- Scalar=magnitude
- vector =magnitude + direction
The correct answer is: Magnitude, vector
- When a physical quantity possess both magnitude and direction it is called a vector quantity.
- While scalar is a physical quantity that has only magnitude.
- A force has both magnitude and direction, therefore :force is a vector quantity.
- Force is measured in newtons ( N ).
