What happens to the reading on the scale as the elevator begins to move upward?

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. On the other hand, when the elevator accelerates downward, you feel lighter.

What does the scale read when the elevator accelerates upward?

The elevator accelerates upward. The inertia of the person would prefer to stay stationary, so the elevator floor and scale must push up on the person to accelerate him upward along with the elevator. … Therefore the Normal Force is larger, so the reading on the scale is a number that is GREATER than the true weight.

What would a scale read in a falling elevator?

The scale reads the Normal force, so it reports your weight as greater than it was at rest. The same two forces are at work as when the elevator was accelerating up. The scale will read the Normal force which is less than it was at rest.

What will happen to a person’s weight when he is in a moving 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. However, when the elevator starts to go or stops, our body resists it. … The same thing works when the elevator starts moving.

What does the scale read physics?

Scales read the magnitude of one of the two forces acting on them, the force they exert on the thing they are attached to. So one scale reads the magnitude of the action force the other scale exerts on it.

How much is your true weight if scale shows 100kg?

The correct unit for force is the Newton (=1 kg·m/s2) which is abbreviated N. So a 100 kg mass really weighs about 980 Newtons on Earth.

Why do we feel heavy when the elevator goes up?

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. On the other hand, when the elevator accelerates downward, you feel lighter.

Do you feel heavier or lighter when riding on 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. In more extreme situations this is much more obvious.

Why do you feel weightless in an elevator?

The phenomenon of “weightlessness” occurs when there is no force of support on your body. When your body is effectively in “free fall”, accelerating downward at the acceleration of gravity, then you are not being supported. … If the elevator cable breaks then both you and the elevator are in free fall.

Why do you feel lighter in an elevator going down?

This can also make you feel lighter: when the elevator slows down, you need to slow down with it. But gravity is always pulling you down, so for you to slow down, the floor needs to push up on you less, so gravity can slow you down. Since the floor pushes on you less, you feel lighter.

Will a fast moving person feel heavier than normal?

According to Special Relativity: The faster you move, relative to another observer, the heavier you appear to that observer. To an observer travelling with you, your mass would remain the same.

Does your apparent weight change when you ride an elevator?

Your apparent weight does not change while riding in an elevator at constant velocity, but it does change while riding in an accelerating elevator. … Your “apparent weight” equals the upward force on you exerted by the floor. If you are moving at constant velocity, your acceleration is zero.

Does weight change with acceleration?

Gravity affects weight, it does not affect mass. MASSES ALWAYS REMAIN THE SAME. Newton’s Second Law of Motion: Force = mass x acceleration The acceleration of an object is: a) directly proportional to the net force acting on the object. … Move it faster (greater acceleration), because there is less mass, or 2.

Is your weight actually your Mass?

Most of the time, when we’re talking about weight, we actually mean mass. Kilograms, pounds, stones, ounces, and grams are all units of mass, not weight. … Weight (red) is how much force acts on your mass. Mass is the amount of matter something is made from.

Can your apparent weight be greater than your actual weight?

For example, when you stand on the floor, the floor exerts an upward force on you. The normal force is always perpendicular to the surface. Apparent Weight is the name given to the force that you exert on another body – perhaps a weigh scale. … Your apparent weight can be greater than your actual weight.

Does scale measure mass or weight?

Scales measure weight, which is the force acting on a mass that is equal to the object’s mass times its acceleration due to gravity. A scale can’t measure mass directly, because the weighing mechanism and the weight of any given object are dependent on local gravity.
