The Physics Philes, lesson 72: You’ve Got Potential

Over the past few weeks we’ve been learning about this super-awesome thing called gravity. In a way, we already know a lot about it because we know about weight and we know about gravitational potential energy. Last week we went a little deeper into the concept of weight and explored …

The Physics Philes, lesson 48: Physicists Make Weird Things for Science

In which I draw a weird thing, do math, and make promises I intend to keep. OK nerds! Class is over, which means it’s time to get down and dirty with some physics. Last time this post had something substantive in it, I discussed the kinetic energy of a rigid …

The Physics Philes, lesson 16: Appreciate the Gravity of the Situation

In which balls are thrown, gravity works, and energy is added. Holy cow, you guys. This is the 16th post of this series and, frankly, I long ago ran out of clever ways to introduce each installment. (You may have noticed.) So I’m just going to jump right into it. …

The Physics Philes, lesson 15: Release Your Potential

In which gravity works, rubber bands are snapped, and energy is conserved. As I hope I’ve proven over the past couple of weeks, kinetic energy is fun and interesting. It helps explain how much energy is needed to move an object. However, we only have part of the story. We …
