Question

12. One object has half the mass of another object. The first object also has half the ---.

a. inertia
b.velocity
c. gravitational acceleration
d. all of these
​

Answer 1

The first object also has half the inertia.

Answer: Option A

Explanation:

Inertia is the tendency of an object to remain in its state. It resists the change in the state of object due to any external forces. So the inertia is the property of an object to resists the change in its state due to any kind of external force. Thus as the mass decreases, the central mass of inertia of the object will also decrease as both are directly proportional to each other.
