So, from the looks of it, we need to define what PE is

PE = potential energy

Potential energy is the energy that is stored in an object due to its position relative to some zero position

In this case, the zero position is the ground.

Potential energy in a nutshell:

The more still you are (and higher from the ground) the more potential energy you will have. That is why it is called POTENTIAL. It has the potential to turn into something else, in this case, when the elephant starts to move, that potential energy will turn into kinetic energy and friction energy.

The equation also helps us better visualize the problem:

PEg = Gravitational Potential Energy

PEg = mgh

So, if you were to increase the height (h) in the equation, then the PE would increase as well, right?

That means if we decrease the height, the PE will decrease. I hope I haven't lost you yet.

This means that 10 m is the highest point, therefore the elephant has the most potential energy at 10 m, so when it starts to fall it will LOSE PE and that PE will be turned into other energies like kinetic energy.

As the elephant falls from 10 m it will lose PE because the PE is at its highest at 10 m, and while it is falling the PE will turn into other energies such as kinetic energy.

Hope this was helpful! There are plenty of great videos about this, I recommend you check them out!

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
