### Segments in this Video

#### What Is Physics?(00:43)

FREE PREVIEW

Physics is the study of how things work. This program will use idealized models of physics.

#### Using Scientific Notation(03:12)

Scientific notation uses exponents to write really big or small numbers. Review how to multiply and divide exponents. Learn how to convert a number into scientific notation, identify common prefixes, and enter scientific notation into a calculator.

#### Using Numbers and Units in Physics(05:23)

Kinematics is the study of motion. Three basic units include time measured in seconds (s), mass measured in kilograms (kg), and length measured in meters (m). Using correct conversion and unit cancellation simplifies results. Walk through a conversion problem.

#### What Are Scalars and Vectors?(03:02)

Hear definitions for magnitude and direction. Scalars are quantities with only magnitude; vectors are quantities with magnitude and direction. View a sample vector on a coordinate plane.

Learn how to use head-to-tail and component methods. Use trigonometry to understand x and y components. Solve an equation using the Pythagorean Theorem to find the magnitude of resultant vector R. Learn the SOHCAHTOA mnemonic and find the R direction.

#### Review of Physics Basics(00:60)

Hear definitions of scalars and vectors. Review adding vectors and finding their magnitude and direction using the component method.

### Description

What is physics? Find out as the Standard Deviants introduce you to the basics, including scientific notation, numbers and units, and scalars and vectors. The Basics introductory video includes the review of the mathematics necessary for the study of physics. To speak the language of physics requires the ability to use scientific notation and to manipulate exponents, plus an understanding of the metric naming convention. A review of the trigonometry and vector addition used in physics is also provided. Don’t panic, though; soon “sines" and "cosines” will seem as natural as “left” and “right.” (Those were once technical terms as well!) Students will feel comfortable with this easy presentation of these necessary skills.
