Answer:
1 PE decrease, Ke Increase, Speed increase, Total remain the same
2 PE decrease, Ke increase, Speed increase, Total remain the same
3) Pe increase, Ke decrease, Speed decrease, Total remain the same
Step-by-step explanation:
If there is no friction in the system, total energy will always remain the same.
Potential energy will increase as your height increases because gravity will have more distance to do work. Potential energy = mgh
Kinetic energy increases as your height decreases because gravity will pull you down transferring potential energy into Kinetic energy
Speed will always do the same thing as kinetic energy, because Kinetic energy = 1/2 mv^2
