1. The problem statement, all variables and given/known data I was reading in a book a little section about orbital velocities. It states: For elliptical orbits, consider a body moving from point A to point B. The total work done by the force on the body is given by W = KE (for B) - KE (for A) 2. Relevant equations 3. The attempt at a solution Since W=Fd, does the KE simply represent the kinetic energy? Thank you.
