In this course you will learn about:
Video 1: Explores what angles are
Video 2: Provides examples of angles
Video 3: Misconceptions about angles
This video explores the angles found in parallel lines.
This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work.
The amount of effort saved when using machines is called mechanical advantage (MA). Simple machines use mechanical advantage as a key property to their functionality, helping humans perform tasks that would require more force than a person could produce. We will use the lever as an example of a simple machine to illustrate the concept of mechanical advantage.
This video explains how to find factors.
In this course you will learn about:
To lay the foundation for understanding what trigonometry is and how it works, do this next activity.
In this unit we will learn how these factors can affect the output of a simple machine. We will also learn about the difference between ideal mechanical advantage (IMA) and actual mechanical advantage (AMA), and how to apply your knowledge to calculate the efficiency of various simple machines.
