This YouTube video will guide you through a fun activity where you will draw the earth's continents and oceans.

This online resource discusses the importance of the ocean, the layers and composition of the ocean and how it moderates climates.

This online resource investigates the features and topology of the ocean floor, the effects of wave erosion and the landforms created by coastal depositions.

An exploration of how the area under a force vs. position graph equals the work done by the force and solves some sample problems.

Outcomes

In this unit you will learn about:

• the concept of work
• understand that work is done by an applied force
• the concept of energy
• identify the different types of energy
• the concept of power

What exactly is energy? How can changes in force, energy, and simple machines move objects like roller coaster cars? How can machines help us do work? In this chapter, you will discover the answer to this question and many more, as you learn about work, energy, and simple machines.

An exploration through some example problems on the concept of work.
