according to this diagram, what is the net force on this object?; what should a free-body diagram look like for a skydiver that is still speeding up as he falls?

Sagot :

There is an arrow up for air resistance and an arrow down for gravity.

The main forces acting on a parachute are gravity and drag. When the parachute is released first, gravity pulls it down, causing it to lunge toward the ground. You can see that the acceleration is negative. This makes sense because the acceleration is dropping.

The object is accelerating downward due to gravity. As speed increases, frictional forces such as air resistance and air resistance increase. At terminal velocity, the weight of the object due to gravity balances the friction force and the resultant force is zero. When drag becomes as great as gravity a force balance is reached and the skydiver stops accelerating.
