Homework Statement
A man is on an elevator
 Draw a FBD of the man if the elevator accelerates upwards
 Draw an FBD of the man if ele. accelerates downwards
Homework Equations
F=m*a
w=mg
The Attempt at a Solution
My FBD For the first one "elevator accelelartes upwards" means that the net force must point upwards, the only two forces acting are the normal force and the weight force. I know that when you go up the elevator you should feel heavier, which is measuring the magnitude of the normal force
So the normal force will have a greater magnitude pointing "up" and the weight force will be a smaller arrow pointing down.. as so..
/\


 Normal force
_

\/Weight force
The second part will be opposite, so you will have a smaller normal force and greater weight force, and will feel lighter than usual because of a smaller normal force acting on you.
First part given by n= may +w
second n=may +w
Is this correct? is something wrong here?
Thanks
