The discussion revolves around calculating the air resistance force acting on a table tennis ball with a mass of 10 g falling at a constant speed of 8.2 m/s. Participants explore the relationship between gravitational force and air resistance in the context of Newton's laws of motion.
The discussion has evolved to a point where participants are recognizing that the forces are balanced due to the constant velocity of the ball. There is acknowledgment of the gravitational force and its relationship to air resistance, with some participants expressing clarity on the concepts involved.
Participants are working under the assumption that the ball is falling freely and that the only forces acting on it are gravity and air resistance. There is a focus on understanding the implications of Newton's laws in this scenario.

Not true. I suggest you think about Newton's Second and First Laws.missmerisha said:
You might want to check you arithmetic, but you're on the right lines.missmerisha said:
... equal to zero: Correct! So if the weight of the ball is mg, what must be the magnitude of the drag?missmerisha said:
