These three short online lessons discuss asteroids, comets and meteors.
Solving a word problem to find average velocity and speed of an object in one-dimension.
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.
