What happens when you stand on a scale in an elevator?

What happens when you stand on a scale in an elevator?

If you stand on a scale in an elevator accelerating upward, you feel heavier because the elevator’s floor presses harder on your feet, and the scale will show a higher reading than when the elevator is at rest. The force exerted by the scale is known as apparent weight; it does not change with constant speed.

What happens to the reading on the scale as the elevator stops moving?

When you stand on a scale, the scale’s reading is a measure of your weight. If the elevator is stopped, the scale reads what you would expect it to read, your weight in an elevator. The same is true when the elevator is moving at a constant velocity. There elevator is in equilibrium.

What does a scale measure in an elevator?

A scale measures the total amount of force pushing down on it, and if you were to step on a scale in an elevator, you would see an increase in its reading.

When you stand on a bathroom scale the scale does not measure the force of gravity?

Therefore, if you were standing on a scale, the scale would read about 3 thousandths less than the force of gravity on you. It is equal to the force of gravity on the book. When you stand on a scale to measure your weight you are pulled down by gravity.

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.

Is the reading on the scale in the elevator higher/lower or the same as the reading in her bathroom?

If you are on an elevator (on Earth), your mass is constant. When the elevator (you) moves up – acceleration increases (adding on to the 9.8ms2 ) and there is more normal force applied to the floor. This results in a larger number on the scale.

What will be the reading of the scale if the elevator is moving up and down at constant velocity?

N = mg if the elevator is at rest or moving at constant velocity. N = mg + ma if the elevator has an upward acceleration. N = mg – ma if the elevator has a downward acceleration.

Does weight change on an elevator?

How much do you weigh in an elevator?

For a passenger elevator, it usually between 100\% and 150\% of the rated capacity – the capacity sign will be in the elevator. These numbers are usually somewhat lower for freight elevators. So a passenger elevator with a capacity of 1000kg will typically weigh somewhere between 1000kg and 1500kg.

What force does the scale read?

Generally, a scale will measure the normal force it supplies to the object resting on it. In the special case where the scale is stationary (as it appears in your picture), this is equal to mg, or the weight of the object.

When a person stands on a bathroom scale the force actually measured by the scale is?

When you stand on a scale, the scale measures your force of gravity AKA weight. This measurement is influenced by Earth’s gravitational force of 9.8N[down] .

Does the scale read normal force or weight?

The force the scale reads will always equal the normal force in magnitude, but not always the weight.

Why does the scale change when the speed of the elevator?

The scale is providing a normal force which counters any force you are imposing on it and thats why the reading changes when the acceleration of the elevator changes (because when the acceleration of the elevator changes your weight changes (because ma=F and when the downward force increases (when elevator is going up) the normal force increases.

Why do you feel heavier in an elevator?

Weight of a Person Riding in an Elevator. If you stand on a scale in an elevator accelerating upward, you feel heavier because the elevator’s floor presses harder on your feet, and the scale will show a higher reading than when the elevator is at rest.

Is the acceleration of the elevator due to gravity equal to?

Snapshot 3: the acceleration of the elevator is downward and equal to the acceleration due to gravity; you and the elevator can be considered to be in free fall, because the scale does not exert any force Take advantage of the Wolfram Notebook Emebedder for the recommended user experience.

What is the force acting on the person in the elevator?

$\\begingroup$ There is a force due to gravity acting on the person in the elevator and a force due to the acceleration of the elevator. These add together and make up the objects weight. They are components of the weight and so there is a component of the weight due to gravity and due to the acceleration of the elevator.
