An introduction to the difference between distance traveled and displacement.

Using a one-dimensional number line to visualise and calculate distance and displacement.

In this course you will learn:

1. What logarithms are.
2. How to apply the log laws.
3. How to simplify logs.
4. How to solve log equations.

Managing time involves accurately predicting how much time it will take to do a task, and then setting aside that amount of time to complete it. Managing time is much more difficult than it may seem, which is why there are entire courses of study and research on the best approaches. But if you develop a method to undertake each component, you’ll be successful.

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

This online resource introduces the geocentric and heliocentric models. Exoplants, planets and their motions, planetary orbits, the role of gravity and how the solar system was formed are also covered. 

This fascinating video details the journey that a group of friends made in Nevada. Their aim was to illustrate the solar system to scale.

Worked examples finding displacement and distance from position-time graphs.
