Question

What is inertial force? How does it acts?

Answer 1

$\huge\bf\red{Hey\:Mate..!}$

Inertia force is also something like that. Imagine you are sitting in a car and the car makes a turn, you will feel a force that's trying to push you out of the door. The car at the turn travels in a circular path, it changes its direction at every instant of time. According to Newton's first law, your body has a tendency to maintain it's motion and resist any changes (that's inertia). As your car turns, your body continues to move in the straight path, the door of the moving car comes in your way and changes your direction. Hence the door comes towards you, you are not moving towards the door. A person standing on the ground can see this. But inside the car you cannot observe this since the frame of reference is also moving with the car. To explain this wrt to car's frame we say that a pseudo force acts on your body that moves you towards the car door. This pseudo force is inertia force, because it is due to inertia of your body.

Answer 2

hey!!

here is ur answer!!


The inherent property of all the objects that they do not change their state of rest or of uniform motion along a straight line path unless acted upon by an external force is called inertia or inertial force

Inertia of body is of three types :

1) Inertia of rest : inability of a body not to change by itself its position of rest.

2) Inertia of Motion : inability of a body not to change by itself its state of uniform motion along a straight line.

3) Inertia of direction : inability of body by virtue of which it tries to resist a change in its direction of motion..

hope it helps!!
