What happens to your apparent weight in an elevator?
What happens to your apparent weight in an elevator?
The normal force is equal to your apparent weight. So, you actually feel a little heavier than usual when the elevator accelerates upward, and lighter than usual when the acceleration is down.
What is apparent weight in elevator?
The sensation of apparent weight comes from the support that you feel from the floor, from a chair, etc. Different sensations of apparent weight can occur on an elevator since it is capable of zero or constant speed (zero acceleration) and can accelerate either upward or downward.
Does your weight increase going up elevator?
When the elevator is moving, we will weigh our normal weight. Since we are already moving at the same speed as the elevator (up or down), nothing is affecting us to change our weight. So for a short time, we are pushed into the floor more and our weight goes up. The same thing works when the elevator starts moving.
How does apparent weight work?
In general, an object’s apparent weight is its mass multiplied by the vector difference between the gravitational acceleration and the acceleration of the object. This definition means that apparent weight is a vector that can act in any direction, not just vertically.
How do you find the apparent weight of an object?
In general, an object’s apparent weight is its mass multiplied by the vector difference between the gravitational acceleration and the acceleration of the object.
Why does apparent weight occur?
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.
Is your apparent weight in an elevator related to your velocity or to your acceleration?
Your apparent weight does not change while riding in an elevator at constant velocity, but it does change while riding in an accelerating elevator.
Do you lose weight in an elevator?
The simplest answer to the question of whether your weight changes when you ride in a lift is ‘no’. Your weight, being the force with which the Earth pulls down upon you due to gravity, does not vary with speed or acceleration. It does, however, feel like your weight changes when you ride in a lift.
What causes the sensation of apparent weight in an elevator?
The sensation of apparent weight comes from the support that you feel from the floor, from a chair, etc. Different sensations of apparent weight can occur on an elevator since it is capable of zero or constant speed (zero acceleration) and can accelerate either upward or downward.
Why does the scale read different weights on different elevators?
Observe that the scale will read a different “weight” depending on the acceleration of the elevator. If it is at rest, the scale will indicate the value of the weight (gravitational force). However, if the elevator ascends with acceleration the scale will read a greater “weight” and if it descends with acceleration the “weight” will be lower.
What is the elevator problem in physics?
Elevator Problem. Elevator Problem. This is an application of Newton’s second lawto the forces felt in an elevator. If you are accelerating upward you feel heavier, and if you are accelerating downward you feel lighter.
How do you calculate support force in an elevator?
support force F= mass x acceleration+ weight For a mass m= kg, the elevator must support its weight= mg =Newtons to hold it up at rest. If the acceleration is a=m/s² then a net force=Newtons is required to accelerate the mass. This requires a support force of F=Newtons.
