The linear momentum of a body of mass m moving with velocity v is —

1. v/m
2. m/v
3. mv
4. 1/mv

The unit of linear momentum is —

1. N s
2. kg m s^-2
3. N s^-1
4. kg² m s^-1

According to Newton's second law, the acceleration produced in a body is:

1. inversely proportional to the force applied on it
2. directly proportional to the force applied on it
3. not dependent on force
4. none of these

Newton's first law of motion defines force :

1. quantitatively
2. qualitatively
3. both (a) and (b)
4. none of these
