Introduction

"For every action, there is an equal and opposite reaction"

Learning about physics could be both fun and a mystery! Newton's Third Law of Motion is one of those laws that is mysterious. Sir Isaac Newton says that, if you push against a wall, at the same time that you move away from the wall, the wall moves away from you. In fact, It is true but this movement is too small to measure.

This action-reaction principle has many applications in real world. In a car accident, in the office, in psychology, in social life, in economy, at the school, while doing sports, in astronomy...etc. You may see it in many forms. For instance, have you ever thought about rockets, scooter, and action-reaction forces together. If no, this webquest is for you (especially for K11 students). Keep going...
