WebMar 25, 2024 · Aristotle further believed that objects fall at a speed that is proportional to their weight. In other words, if you took a wooden object and a metal object of the same size and dropped them both, the heavier metal object would fall at a proportionally faster speed.

WebDec 17, 2024 · The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet. WebJan 17, 2024 · It is always true that in a system where there is no resistance, a falling object hits the ground with kinetic energy that depends on how high it was prior to being let go. Specifically, E k = 1 2 m v 2 = m g h. is how much kinetic energy it hits the ground with if there is no resistance. Note that this is equal to its potential energy as its ...
