To lay the foundation for understanding what trigonometry is and how it works, do this next activity.
An exploration of how the area under a force vs. position graph equals the work done by the force and solves some sample problems.
An exploration through some example problems on the concept of work.
Visualising, adding and breaking down vectors in 2 dimensions.
Defining and comparing tension, weight, friction and normal forces using free body diagrams.
There are many different processes and phenomena that emit electromagnetic radiation. Humans have taken advantage of many of these processes to develop technologies that use electromagnetic radiation.
Photoelectric materials emit electrons when they absorb light of a high-enough frequency.
