Question

can newton's laws of motion be applued for an object moving in a accelerated lift?

explain

Answer 1

yes
Newton's Law of Motion can be applied for an object moving in accelerated lift

Answer 2

When you step into an elevator, you feel like you're the same weight you were when you were waiting in the hallway. When you go up in an elevator, you feel slightly heavier, and when you go down, you feel slightly lighter, if only for a few seconds. If you were to stand on a scale in an elevator, your weight would read slightly different going up, staying stationary, and going down. When you are stationary, your acceleration is 0, so the scale will only read your apparent weight. When the elevator is going up, though, you are accelerating, which adds more force to the scale and increases your apparent weight. When the elevator is going down, the same is true, but the acceleration is negative, subtracting force from the scale and decreasing your apparent weight.
