glass bottles in a recycling plant move along a conveyor belt up to a crushing machine at a constant speed of 0.5 what statement is true about the net force on the bottles as they move

A. The force on the bottles are balanced
B.The forces on the bottles are unbalanced
C.The net force on the bottles is the force due to gravity as they move up the belt
D.The net force on the bottles can only be determined using the mass of the bottles

F = m a = change in momentum/change in time

(again)
if there is no change in velocity there is no change in momentum and the net force on the bottle is zero so the forces are "balanced".

I thought it was moving in a direction so some net force is acting on it to move it

NO No NOOOO !!!!!!

constant velocity is NO FORCE
very, very important

Force = mass * ACCELERATION
not velocity but CHANGE in velocity/time

To determine the statement that is true about the net force on the bottles as they move along the conveyor belt, we need to analyze the forces acting on the bottles.

In this situation, there are two main forces acting on the bottles: the force due to the motion of the conveyor belt and the force due to gravity.

Since the bottles are moving up the conveyor belt at a constant speed, we know that the force due to the motion of the conveyor belt is equal in magnitude and opposite in direction to the force due to gravity. This is because a constant speed indicates that the bottles are in equilibrium, or balanced, which means the net force acting on them is zero.

Therefore, the correct statement is:

A. The force on the bottles are balanced.

There is no need to consider the mass of the bottles to determine the net force in this scenario. The fact that the speed is constant implies that the forces are balanced, regardless of the mass of the bottles.
