Question

Inertia of the body depends on:
(A) Mass of the body
(B) Velocity of the body
(C) Acceleration of the body
(D) Energy of the body

Answer 1

Hint We evaluate the inertia of the body here, so first, we know that by multiplying the mass of the object with the square of the distance between the object and the axis, we determine the moment of inertia, then analyze the variables from the definition of the body's inertia.
Useful formula:
Inertia \[ = {\text{ }}ma\]
Where,
  $m $ is the mass,
  $a $ is the acceleration of the object.

complete step by step answer
Given by,
We find the factor about Inertia of body,
 Inertia is the property of a body that rejects any entity that tries to bring it in motion or if it moves, to modify the magnitude or direction of its velocity. Inertia is a passive property and does not encourage a body to do anything except to resist powers and torques as active agents.
 A moving body tends to move not because of its inertia, but because of the lack of strength to slow it down, alter its direction, or speed it up.
Examples are:
Motion inertia that can be found in our everyday lives includes When seated on a motorcycle in the place of the passenger, the driver's sudden brake application causes the passenger to feel a push in the forward direction. This is because in the forward direction, the passenger is in a state of motion and the inertia of motion still opposes the change in the state of motion.
Hence,
Thus, the inertia of a body depends on multiple variables. The primary factor that impacts a body's inertia is its mass.

Here, option A is the correct answer.

Note Accordingly, when inertia is the resistance to any movement or as mentioned earlier, as the propensity for motion to remain unchanged, we should know what governs its resistance to the action of a force and its moment of inertia to a particular axis, which tests its resistance to the action of a torque around the same axis.
