What is strength?

Force is an interaction of an object with mass, which causes the velocity of the object to change. It can be defined as pushing or pulling a particular object. Force is a vector quantity which means it has both magnitude and direction. When objects interact with each other, it causes a force to push or pull. For example, when you try to push a ball, it is the force acting on the ball that changes its speed. An externally applied force has the ability to change the position of a particular object. The direction in which a force is applied is known as the direction of that force. In this post, we will discuss everything related to force including its formula and types. Refer to the article given below to learn about force.

unit of force

The SI unit of force is Newton (N). However, force can also be defined in various other units as given in the table below.

General indications: F→, F
SI units Newton
In SI base unit: kg m/s2
other units dyne, poundal, pound-force, kip, kilopond
Formulas derived from other quantities F = ma
dimensions LMT-2

effect of force

Whenever a force is applied on an object, it tends to change its shape, size, motion or direction. It changes the speed of an object. Momentum is the movement of a body. Here are some of the effects that apply to its objects:

  1. It changes the direction of an object.
  2. It can change a body from rest to motion.
  3. It can increase or decrease or change the speed of an object.
  4. It can stop a moving body.
  5. It can change the shape or size of an object.

Formula of force:

Force can be found by multiplying mass (m) and acceleration (a). The equation of force formula can be expressed as given below:

F = ma


  • m = mass
  • a = acceleration

It is expressed as Newton (N) or Kgm/s.2 Is taken out in.
The formula to find acceleration “a” is, a = v/t

  • v = velocity
  • t = time taken

Therefore, force can be defined as follows; F = mv/t
formula of inertia p = mv Which can also be defined as momentum.

types of Force:

There are different types of forces that act on an object. Here are some of the commonly applied types of force:

  1. muscular force
  2. mechanical force
  3. Frictional force
  4. gravitational force
  5. electrostatic force
  6. magnetic force

Let us take a look at the types of force in detail:

  1. muscular force

It can be simply defined as the force that we apply on daily basis like we lift, breathe, exercise etc. It acts after coming in contact with the object. This force is caused by the work of our muscles. When we use our muscles to perform daily tasks, the force of the muscles acts on the object.

2. Mechanical Force:

Mechanical forces occur when there is direct contact between two objects where one object is applying a force while the other object is at rest or in motion. Someone pushing a door is an example of a mechanical force.

3. Frictional force

Frictional force is an opposing force between two surfaces whose main purpose is to create resistance for an object moving in the same direction or in the opposite direction. When we ride a bicycle a friction force acts.

4. Gravitational force
Gravitational force is the force of attraction that attracts two objects of mass. Earth's gravitational force pulls us to the ground. It always tries to draw people towards each other and never tries to separate them. It can be defined as Newton's universal law of gravitation.
5. Electromagnetic Force:

The electromagnetic force is also known as the Coulomb force or Coulomb interaction. It is the force between two electrically charged objects. According to this force, just as charges attract each other, opposites repel each other. Lightning is an example of an electrostatic force.

6. Magnetic Force:

Magnetic force is the force that arises between electrically charged particles due to their motion. Magnetic force can be seen between the poles of 2 magnets. It is attractive or repulsive in nature depending on the orientation of the object. This can be called an example of magnetic force (electrostatic force).
