This video explains the angles of elevation and depression.

An introduction to the difference between distance traveled and displacement.

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

Outcomes:

• Design a diet and exercise regimen.
• Estimate the number of calories required for basic survival.

• Explain how Body Mass Index (BMI) depends on weight and height.

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.
