Elevator Physics

Posted by Mr Mallon on March 21, 2009

Here is the latest Higher Physics video where we calculate the weight of a person on an elevator.
Hope you enjoy it.

Answer to the thinking question:
If the lift accelerates downwards at 10 m/s2 then it is in freefall.
This means that R = mg + ma
R = (80×10) + (80 x -10)
R = 0 N weightless!
