Imagine playing a video game that has no motion and everything just sits on the screen and does not move! Thankfully Sir Isaac Newton developed his 2nd and 3rd Laws of Motion. In this 3rd lesson of four, students will create a Unity project that simulates Newtons 2nd and 3rd Laws of Motion.

Introduction

In the last lesson, students explored Sir Isaac Newton's First Law of Motion: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Students created a simulation that hurled spheres in the direction of a stack of cubes and the spheres changed directions when they collided with the cubes. In this lesson, students will build on lesson 1 by reviewing Newton's 2nd and 3rd Laws of Motion, and creating a simulations based on the following:

Newton's 2nd Law of Motion -Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

Everyone unconsciously knows the Second Law. Everyone knows that heavier objects require more force to move the same distance as lighter objects. Just go try and move a car. we all know that this is pretty difficult.

Newtons 3rd Law - For every action there is an equal and opposite re-action. This means that for every force there is a reaction force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard. For example:

 The rocket's action is to push down on the ground with the force of its powerful engines, and the reaction is that the ground pushes the rocket upwards with an equal force.
