Question

Explain the idea of streamlining, as it applies to a skydiver.

Answer 1

Streamlining is a way to reduce air friction. The force on a falling skydiver is due to gravity, minus air resistance. If air resistance is lessened, as by streamlining, the net force (gravity-airFriction) increases, so speed increases.

Answer 4

Newtons first law clearly states that an object at rest will stay at rest unless acted upon by an unbalanced force. Or an object in motion will stay in motion at the same speed and direction unless acted upon by an unbalanced force. Other wise known as the law of inercia.
