If the total net force ona system is zero, assuming the mass remains constant, which must be true?

a. the velocity is decreasing
b. the acceleration is zero
c. the acceleration is increasing
d. the velocity is increasing

1 answer

If the total net force on a system is zero and the mass remains constant, then according to Newton's first law of motion, the object will either remain at rest or continue to move at a constant velocity. This means that there is no change in the velocity, and thus the acceleration must be zero.

Therefore, the correct answer is:

b. the acceleration is zero.
