A person jumps from an airplane with a parachute. Which form of energy is decreasing as the person falls to the ground?A Chemical B Kinetic C Nuclear D Potential

An object is dropped from rest from a certain height. Air resistance is negligible. After falling a distance d, the object’s kinetic energy is proportional to which of the following?

Kinetic versus potential skydiver  |  ProblemA skydiver jumps out of a perfectly good airplane. As she gets closer to Earth’s surface, would you expect her potential and kinetic energy to increase or decrease?  Ignore air resistance in this case. Group of answer choicesPotential energy increases, kinetic energy increases up to a constant value.Potential energy increases, kinetic energy decreases.Potential energy decreases, kinetic energy decreases.Potential energy decreases, kinetic energy increasesPotential energy decreases, kinetic energy increases up to a constant value.

Kinetic versus potential skydiver (2)  |  ProblemA skydiver jumps out of a perfectly good airplane.As she gets closer to the Earth's surface, which of the following best describes the actual transfer of energy?  (So in this case, do not ignore air resistance.) Group of answer choicesPotential energy ---> kinetic energy onlyKinetic energy ---> thermal energy onlyPotential energy   --->   thermal energy onlyKinetic energy ---> potential energy + thermal energyPotential energy ---> kinetic energy + thermal energy

When an object falls faster, its air resistance ______.Multiple choice question.increasesdecreasesremains constant

A person jumped out of a plane and began falling to the surface of the Earth at a rate of 9.8 m/s².The person and their equipment have a total mass of 95 kg.After 30 seconds they have reached a speed of 50 m/s with a kinetic energy store of energy of 118 750 J.During this fall the person has had a change in gravitational energy of 2.3 MJ.Calculate the energy transferred to the surroundings.
