Abstract
In Newtonian mechanics, a mass at rest is supposed to accelerate upwards if it undergoes a force greater than its gravity force or greater than its weight. The forces acting are the weight W downwards and the force F upwards; if F-W = positive, then the force F is greater than the weight W. The net force F-W acting on the mass will be a vector force upwards. A mass can be accelerated upwards with less force than its weight using the leverage concept. In a lever, the force at the load arm is still greater than the load weight; however, the force at the effort arm can be less than the load weight. In this paper, I explain with experimental evidence that a human body uses force less than the human body weight to accelerate upwards by means of biological leverage. The experiment measures the maximum force that a human muscle can exert and shows that this maximum force is less than the human weight, but it lifts the human. I also apply this biological leverage concept to the human body joints, including the human spine's long-term functionality. This theory applies to other living organisms; here, I focus on the human body specifically.
