Answer:
- The weight of the elevator (downward)
- The tension in the rope that pulls the elevator upwards
Explanation:
The elevator is moving at constant speed - this means that its acceleration is zero. Therefore, according to Newton's second law, the net force acting on the elevator is also zero:
[tex]F=ma[/tex]
where
F is the net force
m is the mass of the elevator
a is the acceleration
Since a=0, F=0 as well.
The net force consists of two different forces:
- the force of gravity, which corresponds to the weight of the elevator, which pushes the elevator downward
- the tension in the rope that pulls the elevator upward
Since the net force is zero, the two forces are equal in magnitude, and opposite in direction.
