More than that, it would be free energy. Unfortunately, thanks to the fundamental physics of our universe, perpetual motion machines are impossible.

Learn the key differences between centripetal and centrifugal forces, their real-world applications in physics, and how they shape our understanding of circular motion.

So with these problems, Newton and others had to build this force-motion model through other means. They took a theoretical approach using the data from the motion of the planets orbiting the Sun.

Sir Isaac Newton's three laws of motion describe the motion of massive bodies and how they interact. While Newton's laws may seem obvious to us today, more than three centuries ago they were ...
