Quesiton about terminal velocity
When a sky diver jumps out of a plane he accelerates due to gravity until he reaches terminal velocity when force of air resistance = weight of man due to gravity
When you do free body diagrams to show the forces as the sky diver falls the downward force of the man is always mass * acceleration due to gravity.
So lets say the man is 70kg and his weight is ~ 700N, his force is always 700N. So at terminal velocity when he travels at a constant speed his force = mass * accleration due to gravity.
From a teaching perspective (and from my own too a bit) i think its confusing to explain something is travelling at a constant velocity yet accelerating due to gravity. Any thoughts on this welcomed. In reality i need to ask other teachers about this but I don't have that opportunity yet so i value your expert opinion until then
