## What is Force

Force is a push or pull exerted on the body. We can also define force as an influence causing a body at rest or moving with constant velocity to undergo an accleration. As per Newton's second law

The net force on a body is equal to the product of mass and acceleration of the body

$F=ma$

where

F-> Net Force Acting on the Body

m -> Mass of the body

a -> Acceleration of the body because of the force

Force is a vector quantity .It has both magnitude and direction. The SI unit of Force is Newton

**Example of Few questions where you can use this Force Calculator**

**Question 1**

A Body of mass 4 kg is moving with the acceleration 2 m/s^{2}.Find the force acting on it

**Solution**

m = 4 kg, a =2 m/s^{2}

Now as per force formula

$f=ma = 4 \times 2 = 8 \ N$

**Question 2**

A Force of 10 N acts on the body of mass 2 kg.Find the acceleration of the body.

**Solution**

m = 2 kg, a =? , F=10 N

Now as per force formula

$f=ma$

or

$a = \frac {F}{m} = \frac {10}{2} = 5 \ m/s^2$

**Question 3**

A Force of 50 N acts on the body and the acceleration of the body is 20m/s^{2} .Find the mass of the body

**Solution**

m = ?, a =20m/s^{2}, F=50 N

Now as per force formula

$f=ma$

or

$m = \frac {F}{a} = \frac {50}{20} = 2.5 \ kg$

## How the Force Calculator works

1. If mass and acceleration are given, Force is calculated as

$F= ma$

2. If mass and force are given, acceleration is calculated as

$a= \frac {F}{m}$

3. If acceleration and force are given, mass is calculated as

$m = \frac {F}{a}$
