Is Perpetual Motion Theoretically Possible? Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate either the first or second law of thermodynamics
Can An Object Have Infinite Mass? The energy of a particle diverges to infinity as it approaches the speed of light. Since we can never have infinite energy for a particle, the speed of light cannot be reached. Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has
Is Force And Energy Same? The words energy and force are not interchangeable – they are not the same as each other. A force is a push or a pull which is easily demonstrated and felt but energy is a slightly more abstract concept. They are measured in different units: force in Newton’s and energy
What Frictionless Machine Can Operate Indefinitely? A perpetual motion machine is a machine that can indefinitely do work without the input of any energy. The lure of such a device has caused many hundreds, if not thousands, of people to attempt to conceptualise and build their own perpetual motion machines. Is perpetual motion possible without
Can Something Have Energy Without Moving? Can something have energy without moving? Yes, an object can have energy without having momentum because it can have all potential energy meaning its not moving but it still has energy. Does energy only exist in moving objects? Kinetic and potential energies are found in all objects. If an
