Newton’s Three Laws Newton’s first law of motion: An object moves at constant velocity unless a net force acts to change its speed or direction. Second: Force = mass x acceleration Third: For every force, there is always an equal and opposite reaction force. How do gravity and energy together explain orbits? Orbits cannot change spontaneously.

Unformatted text preview: An objects orbit can only change if it somehow gains or loses orbital energy = kinetic energy + gravitational potential energy (due to orbit). So what can make an object gain or lose orbital energy? Friction or atmospheric drag A gravitational encounter. Rockets....
