Answer
qualitatively
Reason — Newton's first law of motion defines force only qualitatively. A force is that physical cause which changes the state of motion of a body when it is applied on it. It means that force produces acceleration in the body.

The force needed to stop a moving body in a definite time depends on:
- mass of the body
- velocity of the body
- both (a) and (b)
- none of these
Linear momentum is a :
- scalar quantity
- vector quantity
- directionless quantity

According to Newton's second law, the acceleration produced in a body is:
- inversely proportional to the force applied on it
- directly proportional to the force applied on it
- not dependent on force
- none of these
