Question

Explain Inertia and Momentum in detail ?

Answer 1

Hint:Both the inertia and the Momentum are associated with the study of the motion of the solid bodies.They deal with the current state of a body and relate it to the mass of the object.

Complete answer:
Inertia: Inertia can be defined as the characteristic of an object which resists changes to the state of the motion of the object. It is an intrinsic characteristic of the object which is related to its mass which tells us how much force it will take to create the particular acceleration on the object. First law of motion defines the term “inertia” which states the object remains to be in steady or in motion until any external force is applied to it.

Momentum: Momentum can be defined as the function of an object’s mass and velocity. Momentum can be well defined as the measure of the kinetic energy of the object.In simple words, the momentum is the product of mass and velocity.
$P=m \times v$
where, $P$ is the momentum of the body, $m$ is the mass of the body and $v$ is the velocity of the body.

Note: Know the difference between the inertia and the momentum and remember it accordingly. Inertia depends on only mass whereas momentum depends on mass and velocity. The total momentum is conserved whereas, inertia has nothing to do with the conservation of energy.
