Show answer and solution
Answer: (A) 1 only
Inertia is the property of resisting a change in the state of rest or motion, and its measure is mass alone. Statement 1 is correct. Statement 2 is wrong because the mass is the same whether the body moves or not, so its inertia does not change with speed.
