When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).

We know “what goes up must come down.” But WHY? "Drop" in to find out! We know “what goes up must come down.” But WHY? Drop in to learn about the gravitational forces like acceleration and air ...

Like most real-world problems, physics can get very complicated. When a physicist considers the fate of this falling cockroach, their first step is to change the problem into something simpler. It's ...

One of the more memorable student course evaluations I've gotten in my years at Union was from a student in the introductory physics-for-engineers course who complained "They abstracted away all the ...
