Hello everyone! I am by no means a Physicist, I am simply doing research for a new superhero that I am creating and I need to understand the science behind my idea and if it is plausible. A superhero that can channel the rotational force of the earth to add kinetic energy to his strikes/movements. Long story short, hes an Astronaut that's sent to an asteroid for an exploratory mining mission. The asteroid for some reason is gaining speed at a tremendous rate. Turns out it contains a carbon based ore that can absorb kinetic energy from nearby planets and use it for itself. Lab explosion, the ore fuses with his body (both carbon based) and gives him the ability to do the same plus making him practically invulnerable to most physical attacks since his bones are now made of a super strong metal alloy. In a comic book sense does this work? I want it to be somewhat plausible and not too over the top. In order to limit his abilities I was thinking that he must be in contact with the earth in order to use his powers. Buildings and things like that included through transitive logic lol. Would this work into the equation of f=ma?
