When going down in an elevator do you weigh?

When going down in an elevator do you weigh?

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 force does a scale measure in an elevator?

To summarize: the scale will measure the magnitude of the normal force acting on you; which is also the magnitude of the force you exert on the scale (by Newton’s 3rd law). The weight indicated on the scale will only increase as long as the elevator accelerates you upwards.

When riding in an elevator standing on a bathroom weight scale if you are moving downward at a constant speed your weight scale read lower than your normal weight?

The correct answer here is C. The reading on the scale would be less than the true weight of the person. If you were standing on the scale while the elevator was at rest, you would weigh your true weight. The scale would be pushing you upward (to keep you from falling) with a force equal to your true weight.

When you step on a weighing scale on a level ground is the scale’s reading a true measure of your weight?

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] .

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 does the scale read when the elevator is moving up at constant speed?

The scale reads the Normal Force which is opposed by the Force of Gravity on the person alone. Remember: The scale reads the Normal Force, equal and opposite to the Force of Gravity if there is no acceleration.

Is acceleration negative when going down?

Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing. The acceleration is negative when going down because it is moving in the negative direction, down.

What is the acceleration when you throw a ball up?

When you throw a ball up in the air, its direction/velocity on the way up, although it rises up into the air, is actually downward. On its way up, its speed decreases, until it momentarily stops at the very top of the ball s motion. Its acceleration is -9.8 m/s^2 at the very top.

Will a fast moving person feel heavy?

The faster you move, the heavier you get. Energy of motion made you become heavier. This is called mass-energy equivalence.

Why does the scale change when the elevator goes up?

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.

What makes a person feel heavier 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 an elevator up or down?

The overall acceleration is up, so the acceleration is positive. There are two forces in action, your weight down (-mg) and the supporting Normal force. The scale reads the Normal force, so it reports your weight as greater than it was at rest.

Is the weight of the elevator equal to the normal force?

When you and the scale are stationary with respect to each other, these forces balance out and your weight is equal to the Normal force. What if you and your scale are in motion, like in an elevator? If the elevator is stopped, the scale reads what you would expect it to read, your weight in an elevator.
