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).

In many physics problems, we simply ignore the air drag force. Why? Because of two reasons. First, the effects of air drag are often small when dealing with falling balls and rolling carts (a staple ...

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 ...

The first and simplest answer would be "no". When you are skydiving, you quickly reach terminal velocity such that you are no longer accelerating. Maybe the built in GPS could use elevation data, but ...

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 ...
