what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?

a cat and a mouse run down the hallway with the same ke. the faster moving one is the
the faster is the mouse, kinetic energy is a product of squared velocity and object mass, for mouse to have same kinetic energy with a cat, ten must move at a fastr speed
