Like searched the internet and everyone is saying that it is an energy due to speed or something but like I don’t get it. How can something like kinetic energy exists if there is no such thing as speed( I think like speed is no such thing as gravitation or nuclear speed is something else it is not similar like nuclear or gravity)
In: Physics
The important thing is not to think of energy as something tangible like mass. An object isn’t glowing and buzzing filled with kinetic energy. It’s just a mathematic quantity, it doesn’t “exist” as such.
What it describes is, if I were to slow this object down to a standstill, how much work could I make it do? E.g. by letting it push a turbine.
Clearly “standstill” refers to a frame of reference. If you move along with the object, from your point of view you cannot make it do any work and it therefore it has no kinetic energy *to you*. It’s all relative.
