Have you ever noticed how easy it is to do a push-up to lift yourself up and out of a swimming pool?
It’s much easier than doing push-ups on land. That’s because the water is exerting an upward force on you. We can explain with Archimedes’ principle.
states that the buoyant force experienced by a submerged object is equal to the weight of the liquid displaced by the object.buoyant force Fb = Wair- Wliquid = d.g.v
DENSITY is the MASS of an object divided by its VOLUME. The formula is: DENSITY = WEIGHT / VOLUME.
