Question

what is inertia?
resistance of an object to avoid friction
an increase in magnetism
acceleration
resistance of an object to a change in speed or direction

Explanation:

Inertia, in physics, is the property of an object to resist changes in its state of motion (speed or direction). The first option is incorrect as inertia is not about avoiding friction. The second option is wrong as inertia has no relation to magnetism. The third option is incorrect because acceleration is the rate of change of velocity, not inertia. The fourth option correctly defines inertia as the resistance to a change in speed or direction.

Answer:

D. Resistance of an object to a change in speed or direction
