When the momentum of an object increases with respect to time, what is true of the net force acting on it? a. It is zero, because the net force is equal to the rate of change of the momentum.
b. It is zero, because the net force is equal to the product of the momentum and the time interval.
c. It is nonzero, because the net force is equal to the rate of change of the momentum.
d. It is nonzero, because the net force is equal to the product of the momentum and the time interval.

C. It is nonzero, because the net force is equal to the rate of change of the momentum

Explanation:

Momentum of an object is given as;

P = mv = ft

f = mv/t

or f = P/t

where;

P is the momentum of the object

m is mass of the object

v is velocity of the object

f is the applied force on the object

t is time

From the given equation above; the net force acting on the object is equal to the rate of change of the momentum, thus it is non-zero.

Therefore, the correct option is "C"

C. It is nonzero, because the net force is equal to the rate of change of the momentum.
