Is there gravity in space? (it's complicated)

Think there's no gravity in space? Think again. There is LOTS if gravity in space. So why do astronaut's appear weightless? It's a little complicated, but we can use a little math plus a ride from a local amusement park to figure it out. That's right- we're going to Dollywood for this episode!

Nice explaination.

Hey, science teacher here. I like your videos and what you are doing. But there are a few major conceptual errors here.
1. The force of gravity is NEVER stronger on one object compared to the other. Newton's 3rd law applies. Equal and opposite forces. The force of gravity on the ISS from Earth is EXACTLY the same the as the force of gravity on Earth from the ISS.
2. The whole section around the 3 minute mark is full of errors. Centripetal force is not a separate force. It is whatever force is pointing inward, toward the center of the circular motion. Gravity IS the centripetal force for orbiting objects. There is no force pulling the object forward or away from the Earth. Orbiting objects continue to move tangential to the Earth simply due to inertia, no force required to keep them moving, and certainly nothing balancing out to zero.
3. You cite the equation for gravity, mention that it is based on mass, then proceed to plug in a weight in lbs. You also leave out G. And with a mishmash of units, you spit out Newtons. You set it up as an equation with numbers, but as presented it is an invalid equation. If you don't want to get into the full equation, just talk about it as directly proportional to mass and inversely proportional to the square of the distance.
This video would end up reinforcing misconceptions in my students, so I can't recommend it as is. I hope you keep working on it though, just check your physics.
