A skydiver jumps out of an airplane at a high altitude andreaches terminal speed.
Which of the following statements about the falling skydiver atterminal speed is FALSE?
1) The gravitational potential energy of theskydiver-Earth-atmosphere system is decreasing.
2) The thermal energy of the skydiver-Earth-atmosphere system isincreasing.
3) The air resistance force does negative work on theskydiver.
4) At terminal speed, the kinetic energy of the skydiver isconstant.
5) The gravitational force on the skydiver must be larger than theair resistance force in order to maintain a downward velocity.
