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

If the elevator accelerates downward, a is negative, and the apparent weight is less than the true weight. If the elevator falls freely, , and the apparent weight is zero. The apparent weight is zero because when both the person and the scale fall freely, they cannot push against one another.

How does the weight of a person standing in a lift change when the lift accelerates a upwards B downwards with an acceleration A?

If lift is moving upwards with acceleration (a), then apparent weight of a body is more than the true weight. Hence, Apparent weight>true weight.

When lift is going down with acceleration the apparent weight of the body is 1 less than the true weight 2 more than the true weight 3 weightless 4 remain same?

If the elevator is going down with acceleration, the apparent weight of the person is less than the true weight. If the cord of the lift is broken, it falls freely. In this situation, the weight of the person in the elevator becomes zero.

What happens to the weight of a body in a lift which has a net upward acceleration?

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 do you calculate the weight of an elevator?

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

The apparent weight of a person in a lift moving downwards is half his apparent weight in the same lift moving upwards with the same magnitude of acceleration.

What is the apparent weight felt by a person in an elevator?

The apparent weight of a body in an elevator moving with some downward acceleration is less than the actual weight of a body.

When a lift is accelerating up the weight of a man standing on the floor of the lift is?

So, when a lift accelerates upwards, the apparent weight of the person inside it increases. So, when a lift accelerates downwards, the apparent weight of the person inside it decreases. R = m(g – g) = 0. Thus, the apparent weight of the man becomes zero.

What is lift apparent weight?

Apparent weight = Actual weight. Lift moving upward or downward with constant velocity.

What is the apparent weight of a body in a lift?

When a body of mass m is placed on a weighing machine which is placed in a lift, then actual weight of the body is mg. This acts on a weighing machine which offers a reaction R given by the reading of weighing machine. This reaction exerted by the surface of contact on the body is the apparent weight of the body.

What happens to your weight when you are in a lift which goes up?

So, when a lift accelerates upwards, the apparent weight of the person inside it increases. So, when a lift accelerates downwards, the apparent weight of the person inside it decreases. If the supporting cable of the lift breaks, the lift falls freely under gravity.
