Question

If the net force of a system is a non-zero constant and the mass decreases, what must be true about the acceleration?
The acceleration decreases.

The acceleration increases.

The acceleration is a non-zero constant.

The acceleration is zero

Answer 1

F=ma
so, if m decreases, a increases

Answer 2
