This lecture explores weight, perceived gravity, weightlessness, free fall, and zero perceived gravity in orbit. An object is swirled around on a string in a vertical plane. The tension in the string is evaluated when the object is at the top and when it is at the bottom of its circular trajectory.

This lecture is about uniform circular motion. There is a constant radial acceleration (centripetal acceleration) but constant tangential speed

This lecture is all about motion of projectiles (if air drag can be ignored). The objects experience a constant vertical acceleration due to the acceleration of gravity.
