Physical Science

Physical Science is the branch of science that studies the inorganic world as opposed to biology, which deals with the organic world. Physical science has four branches: astronomy, physics, and chemistry.

Forty percent of the GED test will focus on Physical Science.  Therefore, you have to prepare yourself for complicated words and scientific formulas. You may also have to familiarize with some of the laws of physics such as the conservation, transformation, and flow of energy, as well as memorize and understand the definitions of words such as force, work, and motion among others.

Here are some tips to study for the Physical Science component of the GED test:

  1. Know the basics. Physical Sciences have core concepts and theories that you need to understand in order to move on successfully to the advanced topics.

Some of the formulas you may need to memorize are:

  1. physical science formula 1
  2. Work = Force * Displacement * Cosine(theta)
  3. Power = Work / Time
  4. physical science formula 2

Some of the basic laws you may have to study and memorize are:

  • Newton’s laws of motion
  • Law of thermodynamics
  • Einstein’s relativity
  1. Draw a mind map. A mind map resembles a spider web. Drawing a mind map allows you to see how theories are related to each other, so it helps you better understand their meanings and connections. Using drawings or graphics to illustrate theories will also help.
  2. Watch GED video lessons and take GED practice tests. Physical Science includes a wide variety of topics. Watching GED video lessons will help you focus on what are actually included in the GED test, so you don’t have to worry about studying all the physical science topics that you can find. The GED Science Practice Test will acquaint you with the types of questions you might encounter in the actual test. This way, you’ll save time and study only what you need to know.
  3. Which of the following is NOT an example of the first law of motion?
    1. A ball rolling is stopped by friction.
    2. A ball at rest starts rolling when pushed.
    3. A ball does not move even after it was kicked.
    4. None of the above
