Weight on Escalator

will a person moving up in an escalator will feel his weight if the escalator moves in uniform motion (no acceleration)?

Yes, with no acceleration, the total fore on the person must be zero. That means that the downward gravitational force is matched by an upward force from the escalator on the person's feet. That's the same force he'd feel if e was just standing on the floor.
