I have a question, I need your help with understanding definitions. Let's recall the famous problem:
What is the weight of the person mass m, if the elevator moving up with acceleration a?
of course, the answer is N = m(a + g), but according to this https://physics.stackexchange.com/a/436150/222712 (I have checked in the textbooks and I agree).
citing weight is:
weight is the gravitational force that the earth exerts on the body the gravitational force that exerts on a body
So for me in the elevator weight of the person doesn't change, because the force between the earth and person is the same as it was. What changes is the normal force from the elevator's floor. What do you think? please help me with confusion.
