Question

Which one of the following statements concerning the momentum of a system when the net force acting on the system is equal to zero newtons is true?
a. The momentum of the system is increasing.
b. The momentum of the system is decreasing.
c. The momentum of the system is equal to zero kg .m/s.
d. The momentum of the system has a constant value.
e. The momentum of the system has a negative value.

Answer 1

Answer:

D

Explanation:

According to newton's 2nd law rate of change of momentum is directly proportional to the force applied on the body. Since, net Force is zero this means momentum did not change or momentum of the body remained constant.

Hence, the system have constant value of momentum. Therefore, option D is correct.
