What is the apparent weight of a person when an elevator is accelerating upwards?

When a lift is going up with uniform acceleration, the apparent weight of a person is W1​ When the lift is stationary, his apparent weight is W2​

What is your weight if a measuring scale gives you a reading of 50 kg?

So if the scales indicate that your “weight” is 50 kg that really means that your mass is 50 kg. Your weight is your mass times the gravitational acceleration, which is approximately 10 m/s² (more precisely 9.80665 m/s², but it varies slightly depending on your location), so your actual weight is (roughly) 500 newtons.

What will the scale read when the elevator is accelerating downward?

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 is the apparent weight of a man of mass 60 kg?

Since it is moving with uniform speed, there no additional force (a = 0) So, apparent weight = m(g + 0) = (60 kg) × (10 ms-2 ) = 600 N.

Is 50 kg My mass or weight?

If you are looking for the weight of an object, it’s equal how much force an object is pulled down with. 50kg is a measure of mass, which means it is 50kg whether or not it is on the moon or on Earth (it has the same amount of “stuff” in it).

What is the weight of a person whose mass is 50 kg?

The weight of the 50 kg person at the surface of earth is 490 N.

What is a scale in an elevator?

newtonian-mechanics weight. 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 apparent weight of a man of mass 60kg who is standing on a lift which is moving up with a uniform speed?

Explanation: Since it is moving with uniform speed, there no additional force (a = 0) So, apparent weight = m(g + 0) = (60 kg) × (10 ms-2 ) = 600 N.

What is the velocity of the elevator after 5 seconds?

Part C: The Elevator Moves Up With Constant Velocity. The elevator (and you) accelerated for 5 seconds, so it is moving upward with a velocity of 10 m/s. It now moves with this constant upward velocity of 10 m/s. Question 5: What does the scale read now? Answer: There are 2 forces acting on you. (Complete the diagram.)

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.”.

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 happens to your weight when the elevator starts and stops?

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. Let’s say we are going down.
