Determine what forces are present in this situation: am elevator is rising at a constant speed the elevator is the object in this situation

- 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:

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.

temp rises, and expansion

it is a negative acceleration
