Are perpetual motion machines possible?
Is a perpetual motion machine theoretically possible?
What is the significance of having a perpetual motion machine? Can an electric motor run a generator to power its self using semi-perpetual, kinetic motion? If a moving particle had infinite mass at rest wouldn't that mean that whatever speed it has it would have infinite mass or energy everytime? If a moving particle had infinite mass at rest wouldn't that mean that whatever speed it has it would have infinite mass/energy? Will angular acceleration remain constant in uniform circular motion? What is significance of S-N curve to design machine element for finite or infinite life cycle? How does retrograde motion happen? Why is it impossible? If a time machine will ever be made, isn't it true that it has always existed? Conversely, if it was possible wouldn't we have seen evidence by now? Can a body moving in a circular path with constant speed can have variables velocity? Can a body moving in a circular path with constant speed have variables velocity? What is the fastest speed at which a man-made object is capable of achieving (based on the laws of physics)? How could we theoretically enhance speed? Can a body move with constant speed in an accelerated motion? When a simple pendulum is released in a vacuum chamber which was created on earth, does the pendulum stops oscillating or continues indefinitely? Does absolute rest or motion exist in the universe? Must an object moving at a constant velocity have zero net force? When a simple pendulum was released in a vacuum chamber which was created on earth, does the pendulum stops oscillating or continues indefinitely? Is it possible that an alien life form can be a machine? If AI could create simulates on how advanced technology works and had infinite computer power could we create anything with technology? Why is the Earth rotating and will it remain doing so "forever"? Is it possible that humans can built time machines. And if it's been built what are the affirmatives that it can make us travel in time? What is uniformly accelerated motion? What are some examples? Will there will be change in drift velocity if diameter is halved? How would you explain law of conservation of momentum to a layman, using a stationary object and fast-moving object? Will there be any technology in the future allowing people to live forever? Can I change my direction and still have a constant velocity? What is the future of the robotics? How is the future of robotics? For what reasons does uniform circular motion have acceleration? Where is the future of robotics headed?
