In physics, orbital motion is the motion of an object around another object, which is often a star or planet. Orbital motion is affected by the gravity of the central object, as well as by the resistance of deep space (which is negligible at the distances of most orbits in the Solar System).

Sir Isaac Newton described the law of universal gravitation in his work "Philosophiæ Naturalis Principia Mathematica" (1687). The law states that every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them.

can special relativity. The kinetic energy is given by M C. Squared times gamma minus one. So if we want the impart A we want the kinetic energy to be equal to the rest mask. So that means that gamma has to equal to and gamma is equal to one over square root of one minus V squared over C squared help. And if we solve this for V what we get erp We saw this revealed or see what we get is that it's equal to the square root of one minus 1/2 squared in part B. We wanted the kinetic energy to be five times the rest mass. So by this equation, I should say five times the rest energy. So by this equation on when you gamut equal six and the same algebra we went through in part, they will give the the oversea is equal to the square of one minus 16 squared
