What is Perpetual Motion?
A motion of a body which can continue indefinitely till the time an outer force is not applied to restrict its momentum is called Perpetual Motion. A perpetual motion system is a hypothetical system which once starts; can go on and on without applying any energy. This kind of system is practically impossible as it would violate the basic principle of physics and the first and third law of thermodynamics. Though the motion of planetary bodies seems to be perpetual, but after trillions of years, they will also slow down or stop their current motion, as their motion is also impacted by factors such as solar winds and gravitational forces etc.
A perfect perpetual motion machine is impossible in our universe, but scientists and technology geeks keep on trying to make something close to a perpetual machine. There are certain important traits of a perpetual motion machine which include;
Features of Perpetual Motion Toys
- Not having any "rubbing parts", which means that no two parts of the machine should touch each other. The friction caused due to the rubbing of two parts would generate heat, thus lose energy.
- The machine must not be operated in air, but inside vacuum; as the friction caused due to the rubbing of air and parts of the machine would lead to energy loss.
- There shouldn’t be any sound produced while the machine is operating as sound is also a form of energy and if the machine is making sound, it means its losing energy.
Benefits of Perpetual Motion Toys
The momentum toys, also known as Perpetual Motion Toys are a great way to help your children learn about the laws of the universe, few basics of physics, and a glimpse into Newton’s laws; and they would certainly develop an interest in science at a young age. Perpetual motion toys also motivate them towards use of green, clean and renewable energy as these toys can generate energy or electricity from simply a kinetic motion instead of conventional fuels like coal, petrol, diesel, gas or atomic energy. The kids would be interested to know about how an automatic watch (in which the motion of the wearer generates energy to run the watch) works, about new experiments being done by generating electricity from the walking movement of the pedestrians and the way modern trains are using the energy being generated from applying the brakes, back to the source.
Not only for the kids, but even the grown-ups can benefit from the perpetual motion toys as they are a good way of entertainment, concentration, focus, balance and few of them also make for an attractive work desk showpiece. The perpetual motion toys give you a chance to relax and focus back on your task during the short breaks and a few of them even work as fidget toys.
