The branch of science which deals with chemicals is called chemistry.

The energy formed in a system by the motion of particles is called kinetic energy. which is half of the product of the mass and volume.

For example - When someone is riding on an amusement ride also known as a roller coaster, due to the nature of the turns and slope, energy will change from potential to kinetic energy and it will be repeated a couple of times throughout the course of the ride.

The energy stored in the system when it's at a rest is called potential energy, the energy is converted into kinetic energy when it starts moving. The potential energy is stated as the product of the mass, height, and acceleration due to gravity.

For example - Normally, the amusement ride vehicles will be pulled up from the first hill by a chain and as the other vehicles follow that route in climbing, and they will then gain potential energy.

Explained below.

Explanation:

When someone is riding on an amusement ride also known as a roller coaster, due to the nature of the turns and slope, energy will change from potential to kinetic energy and it will be repeated a couple of times throughout the the course of the ride.

Now, Kinetic energy is the one that is used during motion.

Normally, the amusement ride vehicles will be pulled up from the first hill by a chain and as the other vehicles follow that route in climbing, and they will then gain potential energy.

it should be p1 v1 = p2 v2

Answer from: Quest

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
