5 The law of conservation of energy tells us that energy in a system is conserved. This means that the energy doesn't disappear, it's simply transformed into another form of energy or
transferred from one object to another. In the case of this simulation, the girl and her skateboard and the halfpipe are considered the system". How is the energy in this system
"conserved? If the total energy never changes, what happens to it? Be specific and explain which energy transforms into which energy. This should be detailed and in complete
sentences.
Repeat the previous instructions - playing the skater with the friction half way between "none" and "a lot as many times as needed to help you understand how to answer

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
