Demo Title: Newton's Balance
Subject: Resolution of Forces
Description: A 3-4-5 triangle holding a block. Add counterweights and remove the incline.
Procedure:
Place the 1 kg mass on the flat table. The normal force acts vertically upward and is equal to the weight of the object (about 1000 grams of force).
Place the ramp at a 30-degree angle and place the 1 kg mass on the ramp.
The mass stays in place because the normal force (866 grams) counteracts the downward pull (500 grams), keeping the object balanced.
