Is a net force being applied to an object when the object is moving downward under the following conditions?

a) with a constant acceleration of 9.80 m/s2
yes
no
not enough information to decide
Explain.

(b) with a constant velocity of 9.80 m/s
yes
no

Explain.

a) Net force= mass*acceleration. If the acceleration is not zero, then Net force is not zero.
b) Is there an acceleration?

(a) Yes, a net force is being applied to the object. The given scenario states that the object is moving downward with a constant acceleration of 9.80 m/s^2. According to Newton's second law of motion, the net force acting on an object is equal to the mass of the object multiplied by its acceleration. Since the acceleration is not zero, there must be a net force acting on the object.

(b) No, a net force is not being applied to the object. The given scenario states that the object is moving downward with a constant velocity of 9.80 m/s. When an object is moving with a constant velocity, it implies that the net force acting on the object is zero. This is because the object's inertia and the opposing forces are balanced, resulting in no acceleration and hence no net force.
