The extra tension depends not on the velocity of the elevator, but on its acceleration.
The main forces acting on an elevator are gravity, which pulls it downwards, and the tension in the cables or hydraulic system, which lifts it up. Additionally, there may be air resistance and friction that affect the motion of the elevator.
Draw an arrow pointing upwards for the tension force and an arrow pointing downwards for the weight of the elevator which will be its mass times gravity (mg). Also, draw another arrow pointing downwards for any mass that may be inside the elevator (another mass times gravity arrow but for a separate weight) and add that value to that of the weight of the elevator. Depending on the direction that the elevator is moving (up or down) draw another arrow respectively and label it "a" for acceleration.
In an elevator free body diagram, the key components are the elevator itself, the tension in the supporting cable, the force of gravity acting on the elevator and its occupants, and the normal force exerted by the floor of the elevator. The forces involved include the tension in the cable, the force of gravity pulling the elevator down, and the normal force pushing the elevator and its occupants up.
To calculate tension in an elevator cable, you can use the formula T = m*a, where T is the tension, m is the mass of the elevator and its occupants, and a is the acceleration due to gravity. Make sure to consider any additional forces or factors that may affect the tension in the cable.
The tension force in the rope supporting the bucket is also 38N, equal in magnitude to the weight of the bucket. The tension force is required to counteract the force of gravity acting downwards on the bucket, keeping it suspended.

Gravity is responsible for stopping the downward flow of water. As water flows downwards due to gravity, it eventually reaches a point where the force of gravity pulling it downward is balanced by other forces such as friction and surface tension, which prevent the water from continuing to flow downwards.
The tension force in the rope supporting the bucket is also 38N, equal in magnitude to the weight of the bucket. The tension force is required to counteract the force of gravity acting downwards on the bucket, keeping it suspended.
The solution to the physics elevator problem involves calculating the net force acting on the elevator and using Newton's second law to determine the acceleration of the elevator. By considering the forces of gravity, tension in the cable, and the normal force, one can find the acceleration and ultimately solve the problem.
In the activity, I recognized the force of gravity acting downwards on the objects, the force of tension in the strings holding the objects, and the forces of friction between the objects and the surfaces they were placed on.
The main forces that affect a picture hanging on a nail on a wall are gravity pulling the picture downwards, tension in the nail supporting the weight of the picture, and the frictional force between the picture frame and the wall that keeps it from sliding.
The solution to the elevator physics problem involves understanding the forces acting on the elevator and applying Newton's laws of motion. By considering the weight of the elevator and the tension in the cables, one can determine the acceleration and motion of the elevator.
