If Two objects, both traveling in a vacuum, go from point A to B, but one object travels twice as fast - does that take more, less or the same amount of energy?
You don't apply energy to things. You apply forces.Originally posted by MrCaN
The speed at which a object moves is dependent on the energy applied to it.

The statement "both traveling in a vacuum" implies that both objects have a nonzero starting velocity at point A. Therefore it requires no energy for either to get to point B, assuming that point B is along a direct line from point A coincidental to both trajectories. See Newton's 1st law - inertia: particle in motion will remain in motion unless there is a force acting upon it.ando asked:

Basically I don't know what I'm talking about and I really didn't know what I was asking. I really just wanted to know if walking a mile on planet Earth burns more, less, or the same amount of energy as running a mile.
My friend says that if you take a step, it doesn't matter wether you do it fast or slowly, it burns the same amount of energy.]
The myth is that objects will continue to consume energy even in a vacuum, where there is no air or other particles for them to interact with.
This myth is often believed to be true because people have a basic understanding of energy and assume that all objects will consume energy in order to exist.
This myth is debunked by the laws of thermodynamics, specifically the First Law which states that energy cannot be created or destroyed, only transferred. In a vacuum, there are no external sources of energy for objects to consume, therefore they cannot continue to consume energy.
Yes, objects in a vacuum can consume energy if there is an external source of energy present, such as a battery or a power source. However, they cannot continue to consume energy indefinitely without a constant source.
It is important to understand the truth about energy consumption in a vacuum because it helps us better understand the behavior of objects in extreme environments and can prevent misconceptions or false beliefs from being perpetuated. It also allows for more accurate predictions and calculations in scientific experiments and studies involving vacuums.
