How would something being able to go faster than instantaneous or less than zero time speed work? Please, do not say anything about lightspeed (where youe xperience zero time), tachyons, getting somewhere before you leave (causality) and time travel. I am not looking for those. I am looking for how that kind of speed works.

If an object did not have inertia, and a centripetal force acts on it, how fast would it go and what radius would it turn in? Also, could the object turn in the beginning/middle of a turn without slowing down? Also, can something without inertia turn while in the middle of changing direction and do the same thing many times?

Is it totally true, that when Newton's second law (f=ma) is violated, a heavier object when pushed would accelerate at the same rate as a lighter object with the same force? Now don't get me wrong, I do know that physical laws cannot be violated.

How does moment of inertia apply to all the martial arts kicks, punches and other moves?

How is centripetal force applied in gymnastics/acrobatics?

I know the human body is mostly third class levers, making it operate at a mechanical disadvantage. What would happen if the human body were made of first or second class levers?

How do Newton's third law, mass, acceleration, impulse, inelastic and elastic collisions, momentum, conservation of momentum, kinetic energy and conservation of energy go together in terms of interaction?

Every time a gymnast flips, charwheels and somersaults, she has rotational inertia. Now say the gymnast does not have any/zero rotational inertia, how wel would the gymnast perform and how fast would she be able to change her angular velocity (angular speed and direction)? How many times would the gymnast be able to change direction while flipping and turning? P.S.: I know what moment of inertia is; I am just using rotational inertia to use as a property of moment of inertia, like linear inertia is a property of mass.

Even though this is way too impossible, I have a hard time visualizing this; what could a person with 360 degree joints (all joints) do?

I have some questions, 1. What would happen if newton's first law were violated? 2. What would happen if newton's second law were violated? 3. What would happen if newton's third were violated? Also, what would happen if forces were not equal in magnitude and acted in the same direction? I know that in Newton's third law were violated, the conservation of momentum would not be valid. Please don't answer by talking about the conservation of momentum.

I am trying to apply the laws of physics to contortion acts (backbend, splits, etc.) However, I do nkt know what laws of physics apply to the contortionist's flexibility. Could someone please help me out? Also, I mean physics when I say it so I do not a reply saying this should do with biology.
