Question
The inertia of a moving object depends on :
Options
momentum of the object
speed of the object
mass of the object
shape of the object

Solution
mass of the object
The inertia of a moving object depends on the mass of the object. Heavier objects tend to resist a change in their state more than the lighter objects do.

Assertion & Reasoning
- Assertion: The value of ‘g’ decreases as height and depth increase from the surface of the Earth.
- Reason: ‘g’ depends on the mass of the object and the Earth.
Two blocks of masses 8 kg and 2 kg respectively lie on a smooth horizontal surface in contact with one other. They are pushed by a horizontally applied force of 15 N. Calculate the force exerted on the 2 kg mass.
