Will perpetual motion work in space?

If you could pump forever, you would swing forever; but once you remove that energy, you soon stop. Perpetual motion requires an initial force and a sustaining force.” Because even in space there are unbalanced external forces.

Does an object in motion stay in motion in space?

Join NASA and explore the laws of motion in space! Newton’s First Law of Motion: An object at rest tends to stay at rest, and an object in motion tends to stay in motion unless acted on by an unbalanced force. The forces acting on this rocket are balanced; therefore this rocket will remain at rest.

What happens if I throw a ball in space?

If one throws it in the direction of motion, it will speed up and go further out, causing the orbital period to lengthen. It would be at the same spot later then the station. Throwing the opposite direction will cause it to slow down, lowering it’s orbital period, and the ball will arrive first at the spot.

How does spaceships move in space?

The simple act of accelerating something in a particular direction (the rifle bullet or hot gases from a rocket exhaust) creates an equal force acting in the opposite direction (Newton’s 3rd law). This reaction is what propels a spaceship upwards or through space, regardless of the presence of ground or atmosphere.

What would happen if you kicked and flailed in space?

You’d possibly be spinning. In space, no kicking and flailing can change your fate. And your fate could be horrible. At the right angle and velocity, you might even fall back into Earth’s atmosphere and burn up.

Do perpetual motion machines violate thermodynamic laws?

However, these do not constitute perpetual motion machines in the traditional sense or violate thermodynamic laws because they are in their quantum ground state, so no energy can be extracted from them; they exhibit motion without energy. The history of perpetual motion machines dates back to the Middle Ages.

Will a stone move forward in space if there is no friction?

If I throw a stone in space, in a place where gravity is equal zero, and the space had no end, and no objects to collide with, will the stone move forward forever, because no air, so no friction? According to Newton’s first law, yes. The velocity of any object will remain constant if no forces affect it.

What is a perpetual motion machine of the second kind?

A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However, it does violate the more subtle second law of thermodynamics (see also entropy).
