# Forces and Motion

Introduction

Welcome Scientists! This Webquest will guide you through some of the most important things that you need to know in our unit about forces and motion. Complete the tasks below and see how much you can learn about forces and motion.

Task 3: Forces and motion simulation

Process

Task 1: Visit the website at http://www.physics4kids.com/files/motion_velocity.html. Find the definitions of the following:

Force

Velocity

Inertia

Acceleration

Friction

Newton's 1st Law of Motion

Newton's 2nd Law of Motion

Newton's 3rd law of Motion

Task 2: Visit the following website to learn about the life of Isaac Newton.

Summarize the important discoveries that Isaac Newton made in science. How are these discoveries still being used today?

Click on "Forces and Motion Basics." Make sure that you check the boxes for "sum of forces," "value" and "speed."

Experiment with different sized people, different numbers of people, and different distances from the cart. Summarize your observations.

Evaluation

Now that you have learned about the laws of motion, you will show your understanding with this final project.

Watch the following clips from the movie Toy Story 2.

Find one example for each of Newton's laws of motion in the clip. For each law, you will illustrate one part of the video. Then you will write a paragraph to explain what is happening in that clip and how the events you describe in the clip show evidence of that law of motion.

Teacher Page

This Webquest is designed to be an introduction to a unit on forces and motion. The standards addressed here are from the NGSS physical science standards for middle school. Primary standards taught are:

MS-PS2-1. Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.

MS-PS2-2. Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
