This video explains the angles of elevation and depression.

Applying Newton's first law to answer some true/false statements about why objects move (or not).

Solving a word problem to find average velocity and speed of an object in one-dimension.

Patterns and processes of evolution. How evolution and natural selection are reflected in the similarities and differences of organisms. 

In this unit you will apply your understanding of the components of motion in one dimension using linear equations. This will help you to solve problems about motion in one direction and equip you to understand how these concepts apply to everyday life.

There are three equations for linear motion with constant acceleration. They can be used to calculate, and therefore predict, the outcome of motion when three out of the four variables are known.
