When accelerating upwards in an elevator Why do you feel heavier than usual?

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.

How does acceleration work in an elevator?

This is an application of Newton’s second law to the forces felt in an elevator. If you are accelerating upward you feel heavier, and if you are accelerating downward you feel lighter. If the elevator cable broke, you would feel weightless since both you and the elevator would be accelerating downward at the same rate.

When riding in an elevator Why do you lose weight when accelerating downward?

If you are accelerating, Newton’s Second Law says that the net force on you is not zero, which means the upward and downward forces do not cancel. This means that the floor pushes on you with a force that is not equal to your weight – your apparent weight changes.

What is the behavior of light when the elevator maybe accelerating upward or maybe acted by gravity?

Since the accelerated elevator moves up during the time light travels across the elevator, the beam of light strikes low, seeming to the person to bend down. (Normally a tiny effect, since the speed of light is so great.)

Why does normal force increase in an elevator?

From Newton’s second law F=ma, acceleration requires a force proportional to mass. So when the elevator is accelerating upwards, it must not only oppose gravity but provide extra force for the upward acceleration. This requires an increased normal force.

How does acceleration affect normal force?

The normal force generates an upward acceleration. When moving at a constant speed, there is no upward acceleration and the normal force acts only to counter gravity. The normal force, and scale reading, will thus be greater during the period of acceleration.

What causes the light to bend when it passes near a massive object like sun?

Gravity bends light Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects.
