Suppose that when the rock is lowered into the water it displaces water of weight 3 newtons . The force it then exerts on the string from which it hangs would be 10 newtons minus the 3 newtons of buoyant force : 10 − 3 = 7 newtons . Buoyancy reduces the apparent weight of objects that have sunk completely to …

The poundal is defined as the force necessary to accelerate an object of one-pound mass at 1 ft/s 2 and is equivalent to about 1/32.2 of a pound- force . The slug is defined as the amount of mass that accelerates at 1 ft/s 2 when …
