Force and Inertia l my experiences

Describe force and Inertia?

Here I am describing force and Inertia one by one.

force and Inertia

Force

Force is external effect in the form of push or pulls which (i) produces or tries to produce motion in a body at rest, or (ii) changes or tries to change the direction of motion of the body.

Force

Inertia

Inertia is the inherent property of a body, by virtue of which, the body cannot change its state of rest or of uniform motion along a straight line, on its own. It depends upon the mass of the body. Inertia of a body is of three types:
a) Inertia of rest b) Inertia of motion c) Inertia of direction.

Inertia

i) Inertia of rest:

 It is inability of a body to change by itself, its state of rest. This means a body at rest remains at the rest and cannot start moving on its own.

ii) Inertia of motion:

 It is inability of a body to change by itself its state of uniform motion i.e. a body of uniform motion can either accelerate nor retard on its own and come to rest.

iii) Inertia of direction: 

It is inability of a body to change by itself its state of motion a body continues, to move along the same straight line unless compelled by some external force to change it.
