## Statements (A) (B) and (D) are true but the statement (C) is false.

### Explanation :

(A) 2 numerical measures of the inertia of an object : (1) Mass of Object and (2) Momentum of Object.

(B) Rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force according to second law of motion which implies : F = ma

(C) The equal and opposite forces (in III law of motion) act on different objects and on the same objects also according to the third law of motion for ex. Walking on the road, here the force applies on the same object.

(D) Force of Friction always oppose motion of object.
