What Goes Up Must Come Down

Friendly Physics by Gabriela Gallego

Episode notes

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.
