... 1. What is work? As you recall, in science work is defined as force acting over a distance. That is, a force acts upon an object to move it a certain distance. However, to do work according to this definition, the force must be applied in the same direction as the movement. For example, if you lift ...

It is perfectly permissible (and valid) to make a physics model with only a single fundamental variable – physicists already make such a model and use it effectively {11}. So in g ...
