Physics should be simple. It is all around us, relevant in math, biology, sports and space. Let's break it down and listen to ~10 minute episodes on topics ranging from speed to parallel universes. Friendly Physics is produced by a high school physics teacher and steps listeners through kinematics, simple machines, electromagnetism and more.

episode 9: What Goes Up Must Come Down
The past few weeks we have moved on from talking about objects moving horizontally, back and forth, and started to talk about objects that move vertically, up and down
We started off by thinking about objects that fall, like an apple from a tree or a book off a shelf.
Then we started to discuss objects that launch upward, like rockets
And today we are going to connect the two
Because what goes up … must come down
When an object is launched, it goes up and up and up, until it STOPS
And that is where we stopped in the last episode as well
However, in reality we all know that when an object is launched, it goes up and up and up and then it stops and THEN it falls right back down to earth
Naturally, I want to ask some questions about how that object falls.
