It is not possible for a human to swing sword fast enough to create a vacuum. This was a popular theme in many of the Samurai anime. The vacuum create by superhuman speed often lead to devastating attacks in these shows.

Can perpetual motion be achieved using a pendulum in a vacuum?

Yes. In a vacuum, the only resistance is the friction in the suspension for the bob of the pendulum. Other than that, it should swing a long time. In air, friction with air will add to the friction in the suspension and it won't swing as well as it would in a vacuum. But it will swing for a while. A pendulum will swing in water, but the hydrodynamic drag will make it stop in a really, really short period of time. Just a couple of swings will strip the pendulum of almost all its energy. And the speed of the pendulum will be slower than in air, and it won't swing anywhere nearly as far through the bottom of its arc as it did in air.


How does a force change the motion of a carnival swing ride?

Force of tension, exerted from the swing rope, keeps the swing moving in the horizontal back and forth motion. The force of gravity keeps the swing from staying at the far right or far left because it always wants the swing to be pulled to Earth, but the force of tension wants to keep it up. Air resistance, like friction, eventually slows the swing down to a halt.


What is an example of work that you can do to transfer kinetic energy?

One example is pushing a swing. By pushing the swing, you transfer kinetic energy from your body to the swing, causing it to move back and forth. This transfer of energy allows the swing to gain momentum and continue swinging.


Where is the potential and kinetic energy in a pendulum?

The maximum potential energy is at the top of each swing and is at its minimum at the bottom of the swing when it is perpendicular to a horizontal surface. The maximum kinetic energy is at the bottom of the swing, and is at its minimum at the top of each swing. Please refer to the related link below for an illustration.


Why are drawbridges made?

Drawbridges are made to allow boats to pass underneath while still maintaining a pathway for pedestrian and vehicular traffic. They are designed to rise up or swing open to create a gap for taller vessels to navigate through.

How can you make a pendulum swing without stopping Is it possible?

Every time the pendulum swings back and forth, some energy is lost to friction. Friction with air, and friction in the supporting string or whatever. If you manage to reduce this friction (for example, reduce air friction by making the pendulum swing in a vacuum), it will swing longer. However, you won't be able to reduce energy losses completely; it may swing longer, but not forever.
