Question

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

Answer 1

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".

Answer 2

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

Answer 3

NO No NOOOO !!!!!!
constant velocity is NO FORCE
very, very important

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

Answer 4
