When you are standing on a scale in an elevator What exactly does the scale measure?

When you are standing on a scale in an elevator What exactly does the scale measure?

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] . However, in certain situations the force of gravity is equal to the net force: Fg=FNET . This is because mg=ma .

When you are standing on a scale in an elevator What exactly does the scale measure quizlet?

The elevator moves downward while slowing in speed. If you are standing on a scale in an elevator, what exactly does the scale measure? product of the two masses & inverse square of the distance separating the two bodies.

Do you weigh the same in an elevator going up?

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.

What happens to the reading on the scale when 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 are Newton’s laws of motion and gravity quizlet?

Newton’s Law of Universal Gravitation states that all objects in the universe attract each other by the force of gravity. The first law of motion states that an object at rest will remain and an object in motion will remain in motion at constant velocity unless acted upon by an unbalanced force.

How does Newton’s Universal Law of Gravitation explain Kepler’s laws?

How does Newton’s Universal Law of Gravitation explain Kepler’s laws? Universal gravitation implies that the orbits of the planets must be elliptical (Kepler’s first law). Universal gravitation implies that the planets further from the Sun will move more slowly than the planets closer to the Sun (Kepler’s third law).

Does your weight on a scale change 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 is the scales reading during the time that the elevator slows down?

When the elevator is not accelerating when moving upward but is in a uniform motion, the bathroom scale reads the person’s true weight. This true weight is the product of his mass and the acceleration due to gravity which is 9.8 m/s^2.

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

$\\begingroup$ When you are accelerating upwards in an elevator, you feel an increase in apparent weight. 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.

What is the relationship between weight and speed in an elevator?

Your weight would be the same as on Earth, but your mass would be different. Suppose you are in an elevator. As the elevator starts upward, its speed will increase. During this time when the elevator is moving upward with increasing speed, your weight will be __________. Suppose you are in an elevator that is moving upward.

What is the force acting on Me in the elevator?

There are 2 forces acting on you. (See the diagram at right.) The Earth pulls down on you with the force we call your weight (= mg) of 500 Newtons. Since the elevator is at rest, your acceleration is 0 m/s 2. Since your acceleration is 0 m/s 2, Newton’s First Law says the net force on you must be 0 Newtons.

What is the elevator problem in physics?

“The Elevator Problem”. The “Elevator Problem” is a classic problem in physics. The situation is this: “You are standing on a bathroom scale in an elevator. You are holding an apple. (Yes, people are staring at you…) You weigh 500 Newtons, so your mass is about 50 kg.”.
