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.

Outcomes

In this unit you will learn that: 

• Osmosis is the movement of a liquid from an area of high concentration to an area of low concentration until it reaches equilibrium.

The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!

The model also helps us to understand what happens to the particles when matter changes from one state to another.

This is a short tutorial on how to define and measure the perimeter of shapes

By the end of this course you will be able to:

1. Define the terms perimeter and area
2. Find the perimeter of any polygon
3. Find the perimeter and area of a trapezium, parallelogram, rectangle and square
4. Find the area of a triangle
5. Find the perimeter and area of a circle

In this unit, you will explore the three phases of matter and then look at the properties and differences between them. You will explore their shape, volume, and kinetic energy.

Photoelectric materials emit electrons when they absorb light of a high-enough frequency.

Using position-time graphs and number lines to find displacement and distance traveled.

The potential energy between two objects due to long-distance forces can be thought of as being stored in a field. When the objects move due to the field forces, the energy stored in the field decreases

Outcomes

In this course you will learn about:

• The concept of pressure
• Pressure due to solids
• Pressure in liquids
• Atmospheric pressure
