Alright so astrophysics is the a newer, badder and more kick ass version to astronomy. Astrophysics delves into the physical laws and properties of the universe and all celestial beings (galaxies, planets, stars, etc.) Astrophysics is a branch of physics that incorporates numerous disciplines of physics, such as mechanics, relativity, electromagnetism, particle physics and thermodynamics. With our current knowledge of mechanics, we would have a very hard time trying to create equations of the movement of celestial beings.

So today we learned about Newton's Laws. Now we all know what Newtons Laws are: First Law: An object at constant velocity will remain at a constant velocity unless a net force acts on the object; an object at rest remains at rest remains at rest unless a net force acts on the object.

Second Law: Force is equal to mass times acceleration F=ma

Third Law: Every object has an equal and opposite force on two separate objects.

Newton was a genius in his own right. But his laws of motion had certain problems when considering the movement of celestial objects. Although being the father of integral and differential calculus, Newton found constraints when dealing with multiple two body equations (Newton's Third Law).
