You've seen a movie at some time when there were skydivers falling through the air, spread out, doing their tricks.  At times there are many falling together.  They look like they're barely moving.  How fast are they actually moving through the air, typically? (your source?)  If they're moving that fast, how can they hook up and touch each other without getting hurt?  Finally someone pulls the cord to open their chute and ...zip! Up they go.  Does a skydiver go up when their chute opens like it looks in the movies?  What's going on?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
