Question

Force is a .............quantity.
A. Vector
B. Scalar
C. Tensor
D. None

Answer 1

Hint:A force is basically either a push or pull upon an object which results from the interaction of an object with the other object. Whenever two objects interact with each other, there is always a force acting upon each of these objects.

Complete step by step solution:
 Let’s start with term quantity. The quantities which we can measure
are known as the physical quantities.
1) Scalar quantities
2) Vector quantities
3) Tensor quantities

Scalar quantities: The physical quantities which have magnitude but no direction then it are called scalar quantities. For example: Mass, energy, current etc.

Vector quantities: The physical quantities which have both direction and magnitude then its called vector quantities. For example: Force, Displacement, Velocity etc.

Tensor quantities: When physical quantities are described with respect to a coordinate system then those quantities are called as tensor quantities or we can say that quantities which show some time vector properties and some time scalar properties. The physical quantities which have magnitude, direction and plane in which it acts. For example: a stress, a strain, etc.
Now, Force is an external medium that changes the state of rest or motion of a particular body.

Force has both magnitude and direction. The direction towards which the force is applied is called direction of force and where the force is applied is called application of force. SI unit: Newton.

The quantity of force (F) is expressed by the vector product of mass (m) and acceleration (a)
\[F = m*a\]

The correct answer is Option A i.e. vector.

Note:We can say that force is a vector quantity because it depends on that direction in which we apply the force. For example: If we walk opposite the direction of wind we observe that it’s hard to walk against the winds but if we walk the same as the direction of wind then we observe that it’s easier to walk. So we need to know first in which direction the wind is blowing and the direction in which we are walking, so we can say that the force is directional.
