Chapter 4: Forces and Newton`s Laws of Motion
... The free body diagram (FBD) is a simplified representation of an object, and the forces acting on it. It is called free because the diagram will show the object without its surroundings; i.e. the body is “free” of its environment. We will consider only the forces acting on our object of interest. Th ...

... If you accelerate down (in the direction of gravity) at a rate of 10 m/s2 you will feel 100% lighter, which is called “free fall”. We’ll use this concept to calculate the tension in the elevator cable for this problem. So you noticed when the pulley was stopped the tension in the lines was not equ ...
