What are the two main branches of physical science?

There is a PhD in Materials Science and Engineering.She has taught physics, chemistry, biology, and mathematics.

Stars, cans, water, rocks and baseballs are all physical objects.The physical sciences want to understand the behavior of objects.Everything that isn't alive is within the physical sciences.The life sciences and social sciences deal with living things and people.Scientists break the physical sciences up into subfields because this leaves a lot of ground to cover.

Geology, astronomy, and meteorology are some of the other physical sciences.All sciences rely on the results of physics and chemistry.The study of the physical universe is broken into the two most fundamental areas.Let's take a closer look at more detail.

The laws of motion of objects are dealt with in physics.A physicist is most interested in finding out how a system changes over time.If you throw a baseball through the air, a physicist would want to measure all the forces involved with the throw and be able to predict the path of the ball at each point in time after it left your hand.A physicist would like to know how air flowed past an airplane wing or the hull of a boat.

The nature of space-time is something physicists are interested in.This may seem abstract, but the smallest pieces of the universe are very small.Physicists have found that matter is made up of atoms.Particles and quarks are also made of smaller pieces.

It is difficult to find the fundamental building blocks of matter.Scientists from many countries have come together to build large machines that slam particles together at high speeds to increase their knowledge.It's similar to ramming two cars together and figuring out what they were made of.

The movement of distant stars and galaxies can help us understand space-time.Physicists don't see space-time as empty, it's more like a lightly curved surface.Physicists now know that a star's gravity can bend space-time and cause light to bend around it, allowing us to see objects behind it.The same physics responsible for bending starlight is needed to accurately calculate the time sent from Global Positioning System (GPS) satellites to Earth.

Chemistry deals with the internal properties of matter.A chemist is interested in how to create new chemicals from existing substances using a variety of methods.There are only a few hundred chemical elements on the periodic table, but they can be combined in many ways.Carbon, hydrogen, oxygen, and nitrogen make up most of the living things on the planet.

A chemist would like to know how baking soda andacetic acid and water come together to release carbon dioxide.An example would be the lead and sulfuric acid in a car battery and how electric charge can slowly transfer from one to the other.

Chemists want to discover the chemical composition of unknown compounds.They use a lot of scientific instruments to gather information about chemicals.A series of chemical reactions can be used to see if a chemical behaves in certain ways.

Most explanations of chemical reactions don't require anything smaller than atoms, in fact different types of atoms were first discovered and organized by chemists into the periodic table.Nuclear chemistry and acid-base chemistry use protons, neutrons, and electrons.

There are areas of overlap between physics and chemistry.The laws of physics underlie chemistry, and the attempt to connect the underlying theories of atomic models to explain chemistry can be studied by both physicists and chemists.

Chemical systems can be subject to scientific experiments because they are too complex to apply the laws of physics directly.The laws of how chemical reactions work have been worked on by many physicists.The liquid crystal display screens in TVs and monitors are studied by physicists and chemists.

The movement of physical objects in time and chemistry's ability to change physical matter from one type to another are both related to physics.Both are concerned with what matter is made of, but physics looks at this question on a much smaller scale.

There is an overlap of chemistry and physics in many areas.Launching a vehicle into space where the thrust provided by a propellant launches the rocket upward is one such area.Physical forces govern the movement of the rocket.

Newton's third law states that for every reaction, there is an equal and opposite reaction.

The upward movement is called the motion in the illustration.The motion is opposed by gravity and relates to the first law of inertia.Unless acted upon by an unbalanced force, an object at rest stays there.The unbalanced force applied to the rocket is the thrust.The upward force from the thrust needs to be bigger than the downward force of gravity.To launch a rocket.

A chemical reaction provides the thrust for a rocket.The fuel and oxidizer make up the propellant.The oxidizer is oxygen gas and the fuel is hydrogen gas.By the following reaction, the two combine to produce steam.

A huge amount of energy is released from the formation of the steam.The amount of energy is related to thermochemistry.

1.Unless acted upon by a(n) _____ force, an object at rest stays at _____.

3.In order for a rocket to move upward, the thrust needs to be greater than the pulling it down.

5.Write about a liquid rocket reaction.Balance the equation and indicate the phases of each reactant and product.
