Final answer:
Real-life experiments consistent with the described energy transfers include lifting an object, throwing a ball upward, water falling onto a turbine, and compressing and releasing a spring.
Step-by-step explanation:
a) An experiment that is consistent with the energy transfer described in a) would be lifting an object off the ground. When you do work by applying a force to lift the object, the object gains kinetic energy.
b) A real-life experiment that shows the conversion of kinetic energy into gravitational potential energy is throwing a ball upward. As the ball is thrown upward, its kinetic energy decreases while its gravitational potential energy increases.
c) One example of the conversion of gravitational potential energy into thermal energy can be seen when water falls from a height and hits a turbine. The gravitational potential energy of the falling water is converted into thermal energy due to the friction between the water and the turbine.
d) An object's gravitational potential energy can be converted into elastic potential energy in an experiment where a spring is compressed vertically and then released. The gravitational potential energy of the object is converted into elastic potential energy of the spring as it returns to its original shape.
