As a sky diver falls faster and faster through the air (before reaching terminal speed), does the net force on her increase, decrease or remain the same? Does her acceleration decrease, imcrease or remain the same?
1. Force = mg. m and g are constant.
Therefore, the net force is constant.
We are neglecting air resistance.
2. The acceleration is assumed to be constant at 9.8m/s^2. But the velocity increases with distance.
