To lay the foundation for understanding what trigonometry is and how it works, do this next activity.
In this chapter, you will learn why it is important to identify a reference frame in order to clearly describe motion. For now, the motion you describe will be one-dimensional. Within this context, you will learn the difference between distance and displacement as well as the difference between speed and velocity. Then you will look at some graphing and problem-solving techniques.
This video explores the different types of angles that exist.
Defining and comparing tension, weight, friction and normal forces using free body diagrams.
Visualising, adding and breaking down vectors in 2 dimensions.
In this unit you will learn what a force is and find out about different types of forces. This will allow you to identify forces at work in your everyday life and understand the effects of forces.
