Fluids and forces can be a bit tricky at times.  If you break their brhaviors down to a few key concepts, it’s really not all that daunting. All fuids exert a downward pressure that increases with depth. The reason is fairly simple - gravity pulls...

Momentum is a force associated with moving objects. When objects move, they do so with a certain amount of energy - this is essentially what momentum is. Momentum is the product of the mass and velocity of an object (P = mv). So, for two objects...

One of the most important, but often overlooked, aspects of the world around us is the weather. It has an impact on everything in our lives – from what we wear day to day, to whether or not we are able to eat! So what is it, really? Weather is the...

Good old Isaac Newton developed a law or two that we use to describe motion in physics. Newton’s First Law of Motion: Objects in motion tend to stay in motion, objects in rest tend to stay at rest. Basically, Newton claims that objects are stubborn...

Let’s start off with something neat: What exactly is gravity then? We experience it every day - take it for granted even - but most of us aren’t really all that familiar with the facts about it. So how about a definition: Gravity: the force that...
