Newtons Gravity Glass is a sand-filled hourglass suspended in a liquid-filled glass cylinder. The Gravity glass is an awesome desk-topper and a question-generating educational tool. When the cylinder is flipped, the sand within the hourglass moves down while the hourglass itself floats up.
Newton’s three laws of motion relate the forces acting on a body to its motion. The first is the law of inertia, it states that ‘every object in motion will stay in motion until acted upon by an outside force’. The second is commonly stated as ‘force equals mass times acceleration’, or F = ma. The third and final law is commonly known as ‘to every action there is an equal and opposite reaction’.
