I think it's more convenient to watch in this video length as many things are covered in just one video but I think it would be better for your channel if you break it up in parts and then upload those shorter videos and at last I wanna say your work is amazing, thank you for this✌🏼

@@accountforscienceandmathem3333 Thank you, I appreciate the feedback! I think I'll continue uploading full videos and shorter clips like you said, that way people have both options for watching/sharing

awesome teacher i have ever encountered

Thanks

I think it would have been better to choose the sign of parameters according to the gravitational force. It is so understandable but thanks for the good work ❤

I still don't understand why we always use (-g) whether the object is going up or down

[@physicslab42]

Yeah that's a common point of confusion. The acceleration of g (9.8 m/s²) is caused by gravity, which always acts downwards no matter what's happening, gravity and the acceleration never act upwards. So even if an object is moving up (it's velocity is up) the acceleration is still down. That has the effect of slowing down the speed of an object moving up, and speeding up an object if it's moving down. Does that help or still confused?
