Question

Is force a energy?


Open in App
Solution

Explanation:

  1. A force is an external agent capable of changing the state of rest or motion of a particular body.
  2. Push or pull of an object is considered a force
  3. Being a vector quantity, a force has both magnitude and direction.
  4. When labor is performed or heat is applied to something, energy is the quantitative property that must be transmitted to the object. A conserved quantity is energy.

Let us imagine a block is placed on a frictionless horizontal plane. If an external agent applies a net force (F) that causes a body to move, the energy required to do work (W) is determined by the "D" units as follows:

W=F·d

The displacement is measured in m, while the force is measured in kgm-2.

A physical system's ability to accomplish activity is called energy. Energy may be changed into other forms, but it cannot be generated or destroyed.

The SI unit of energy (E) is therefore given by,

E=kgms-2mE=kgm2s-2

Observe that it is more accurate to differentiate between force and energy based on their fundamental units.

Therefore,

  1. The terms energy and force are not interchangeable; they are not synonymous.
  2. A force is a push or a pull that can be seen and felt, whereas energy is a slightly more abstract term.
  3. Force is measured in Newtons, while energy is measured in Joules.

Hence, force is not energy.
