What is the apparent weight of a person when an elevator is accelerating downward?

The apparent weight of a person in a lift moving downwards is half his apparent weight in the same lift moving upwards with the same magnitude of acceleration.

What happens to the apparent weight of the person inside the lift moving with net upward acceleration?

Answer Expert Verified. When the lift accelerates upward, a pseudo force will act on the body in the downward direction in addition to the weight. So the apparent weight will increase. So the apparent weight will be same as the real weight.

What is apparent weight of an object?

In physics, apparent weight is a property of objects that corresponds to how heavy an object is. The apparent weight of an object will differ from the weight of an object whenever the force of gravity acting on the object is not balanced by an equal but opposite normal force.

What is apparent weight equation?

Usually, an object’s apparent weight is its mass multiplied by the vector difference between the acceleration of the object and the gravitational acceleration. This definition means that apparent weight is a vector that can make a move in any direction, not just vertically. Thus, apparent weight formula; a = dv/dt.

What will be the apparent weight of the object when the lift moves with a constant speed v downwards?

Now, since question says that lift is moving with constant velocity v , the value of “a” = 0 m/s². So, apparent weight will be equal to weight of the body.

What is apparent weight in elevator?

Note: Apparent weight is the weight you ‘feel’. When you are falling, you feel weightlessness. Thus, the Apparent Weight is 0. When in an elevator going upwards with growing speed, you feel heavier. Therefore, more is the Apparent Weight!

What is apparent weight in simple words?

Definition of apparent weight : the weight of a body as affected by the buoyancy of a fluid (such as air) in which it is immersed, being the true weight minus the weight of the displaced fluid — compare archimedes’ principle.

How do you find the apparent weight of an object?

The net force experienced is the vector sum of these two forces. This force becomes your apparent weight, which points in a direction backward and down. The apparent weight of an accelerating object is the vector sum of its real weight and the negative of all the forces that produce the object’s acceleration a = d v /dt. wapparent = wreal – m a.

How does your apparent weight change when you accelerate?

In the accelerating frame of the car, you experience the fictitious force in the backward direction and your weight, pointing down. The net force experienced is the vector sum of these two forces. This force becomes your apparent weight, which points in a direction backward and down.

What is the acceleration of the lift as it moves upwards?

The lift moves upwards at an acceleration of 1 1 m⋅s−2 m·s − 2. If the lift is accelerating, it means that there is a resultant force in the direction of the motion. This means that the force acting upwards is now greater than the force due to gravity →F g F → g (down).

How is weight measured in physics?

Weight is measured through normal forces. When the lift accelerates upwards you feel a greater normal force acting on you as the force required to accelerate you upwards in addition to balancing out the gravitational force. When the lift accelerates downwards you feel a smaller normal force acting on you.
