What is the force?

Force is an external effort in the form of pushing and pulling, which creates motion in an object or stops a moving object and changes the motion of the object.

Example of Force

1. When we push a ball lying on the ground, it starts rolling.

2. Our hands can be easily caught when a ball falls downwards.

Galileo's laws of inertia -

If a net external force is zero, a body continues to rest and in equal motion, a body moves evenly along the same straight line.

What is Inertia) - The property of all bodies, on the basis of which they cannot change themselves from their state of rest or a state of uniform motion along a uniform line, is called inertia.

Type of Inertia -

1.Inertia of Rest - It is the inability of a body to change by its self, it's a state of rest. this means a body at rest remains at rest and cannot start moving on its own, Rather, a body at rest opposes the force that tries to move it.

for example - when a horse starts, suddenly, the rider tends to fall backwards.

2. Inertia of Motion - It is the inability of the body to change by ,it's self it's a state of uniform motion. that is a body in uniform motion can neither accelerate nor retard on its own and come to rest , rather, a body in uniform motion opposes that tries to stop it.

for example - when a horse full gallop stops suddenly, the rider falls forward on account of inertia of motion.

3. Inertia of Direction - It is the inability of a body to change by its self, it's the direction of motion, that is a body continues to move along the same straight line unless compelled by some external force to change it, rather, a body opposes the force that tries to change the direction of motion.

for example - The rotating wheels of any vehicles throw out mud, due to direction of inertia.

Newton's Laws of Motion ) -

First Law of Newton - a body continues to be in its of rest or of uniform motion along a straight line unless it is acted upon by some net unbalanced force to change the state.

Second Laws of Motion - The rate of change of linear momentum of a body is directly proportional to the external force applied on the body and change takes place in the direction of the force applied.

F = ma ( where F is the Force, m= mass, a= acceleration of the object.)

Third Laws of Motion - To every action, there is always equal to the opposite reaction. that is the force of action and reaction are always opposite.

F12 = F21

Explanation of Newton's Second Law -

suppose two bodies of different masses are initially at rest and a fixed force is applied on them for a interval of time . to start with , the lighter body picks p a greater speed than the heavier body ,Hhowever, at the end of the time interval, observation show that each bodies acquires forces.
