During a pass, a football's mechanical energy is potential energy. Mechanical energy is "potential" for any object in motion that is not moving itself (the football is displaced by the player).
a wave that is required to pass over a energy of alot of things
Mechanical waves can't pass through a vacuum. Mechanical waves need something to pass through. Space is generally considered a vacuum, with nothing in it to transmit a mechanical wave.
Never. Sound propagates as longitudinal waves which are a kind of mechanical waves. These waves require a medium for them to pass. The medium can be either solid, liquid or gaseous. Thus, in empty space i.e. vacuum, sound can never pass.
No. A light switch merely allows energy to pass, or not to pass.
One way to look at this is that there are three basic mediums: solid, liquid and gas. You may want to add plasma as a fourth. These are exciteable mediums. When we study mechanics, we look at mechanical energy and these dynamic mediums. Certainly the material or materials that make up a medium can vary. Air for example. It is composed of a number of gases and other things. But it is treated as a gaseous medium through which sound waves, which are mechanical energy, pass. Sound will pass through solids, liquids and gases, and will suffer varying rates of attenuation. The sun is a ball of plasma, but waves have been seen rippling across its surface. The plasma is a medium across which the wave, which is mechanical energy, can pass. Just like a ripple on a pond. A vacuum might be added to the list, but justification would be thin. Light, which is electromagnetic energy, will pass through a vacuum. No mechanical energy will. There are other criterion for mediums, like mediums for storing, say, digital information. Punch cards or punched tape? Magnetic tape or disc? Optical disc? The physics of data storage is advancing in its ability to hold more date in less space.

no
The role of quarterback in American football is an offensive back whose primary role is to pass the ball during a play.

I cannot speak to those specific rules of football, but in general, lineman are allowed to be downfield on any pass where the ball is caught BEHIND the line of scrimmage.
No, it is ruled an incomplete pass
A mechanical wave travels through a medium because a medium is necessary for the propagation of that wave. With a mechanical wave, like sound, mechanical energy is put intothe wave, and the medium carries the energy of the wave. This is in contrast to an electromagnetic wave (like light) which can move through a total vacuum.
The spiral pass is the most accurate.
Never. Sound propagates as longitudinal waves which are a kind of mechanical waves. These waves require a medium for them to pass. The medium can be either solid, liquid or gaseous. Thus, in empty space i.e. vacuum, sound can never pass.
instep pass
In American football and Canadian football a lateral pass or lateral (officially backward A lateral pass is distinguished from a forward pass, in which the ball is after taking the snap, to quickly transfer. The Canada football is not the NFL. That's what I asked.
