Whoever answers correctly gets brainliest which of the following happens when the swing moves from position b to position a? [ ] both potential energy and kinetic energy of the student increase. [ ] both potential energy and kinetic energy of the student decrease. [ ] potential energy of the student decreases and kinetic energy of the student increases. [ ] kinetic energy of the student decreases and potential energy of the student

its c

Explanation:

Total energy is conserved.

Energy = potential energy + kinetic energy as other forms of energy are neglected.

Clearly , position A is at a higher position from the ground , so it has more potential energy.

As the energy is conserved , the kinetic energy at A must have decreased making the total energy the same as that during B.

So,to sum it up  

potential energy of the student increases and the kinetic energy decreases as he moves from B to A

ill do it for 100, also this isnt 80 its 40
