## 5 Newton's Laws

Newtons law describes the body's motion in terms of physics .It has been widely accepted by the science community for the past century, in total there are three laws that affect the laws of motion. This indicates that the projectile is moving.

1. Matter does not change its state when there is no force apply to it
2. Matter changes its state when there is force apply to it
3. To remain in equilibrium, the total force act on matter must be zero
4. Matter will generate opposition force to oppose force apply
5. The attraction force between 2 objects is indirectly proportional with seperation distance between 2 objects

## Newton's First Law

A body remains at rest or in uniform motion until and unless an external force acts upon it (Unbalanced force)

Newton first law of motion is called the law of inertia . The basis of this law means that if an object is not moving it will only move when a force is applied onto it, as well as an object that is in motion will not change its velocity (accelerate) until a net force acts upon.

${\displaystyle F=0}$  . Matter is stationary or at rest . It does not move

## Newton's Second Law of motion

Newtons Second law is the law of Interaction in which he Doubted;

```Matter changes its state when there is force apply to it
```
${\displaystyle F=ma}$  . Matter goes into motion from stationary state

## Newton's Third Law of motion

All forces occur in pairs, and these two forces are equal in attitude and opposite in direction.

Newtons third law is the law of Equilibrium . This in simple terms is that to every action force there is an equal, but still the same, reaction force. For example if one presses on a wall an equal, and same force, is pushed back at them.

It can be said that "every action has opposite and equivalent reaction

${\displaystyle F_{-}=-F}$
