Name:
Score: ________/25
1. Using any search engine (www.google.com, www.bing.com, etc) research the name of the scientist
who gave the scientific world three laws of motion that we still follow and teach today.
Use the following link and click through the presentation to answer the questions – First Law of Motion
2. What is this law known as? In other words, what is its name?
3-4. The First Law of Motion has two parts. Describe the meaning of both parts of the First Law of Motion.
5. What does “unless an external unbalanced force acts upon it” mean? Hint: think about what is
happening to each object at rest in the presentation.
6-7. Slide 6 of the presentation begins the second part of the First Law of Motion. List two ways to move
an object traveling at a constant speed in a straight line?
8. The presentation frequently discusses the use of an external force. What were three examples of an
external force described in the presentation? Hint: External force was used in parenthesis at the bottom
of some of the slides.
9-10. List or describe two other examples from our world of external or unbalanced forced that would
affect a moving object.

11. This presentation is very confusing!!! But in fourth grade, we want you to understand the word
acceleration. Think about where you have heard this word before? What about accelerate or accelerator
(like in a car or truck)? Explain what you know about the word acceleration (This is NOT the speed).
12. What is this law known as? In other words, what is its name?
13. An object with a large force will have what?
14. An object with a small force will have what?
15. An object will always move in the direction of the what? Hint: See slide 4.
16. Explain how the mass of an object affects the acceleration of that object.
17. How could you determine, or find the acceleration of an object? Hint see slide 10.

18. Describe what this law states?
19. A rocket is a great example of this law. How does a rocket work?
Use the following link to answer the questions – Two Types of Energy.
20-22. What are the two types of energy related to Newton’s Laws of Motion? Describe them. List a few
examples of each.
Using your knowledge of potential versus kinetic energy, click on – Quia Quiz and answer the questions.
23 – 25. In fourth grade, we study three terms related to moving objects – SPEED, VELOCITY, and
ACCELERATION. Watch this short video on Motion and in your own words, explain what these three
terms mean. You should be able to see their differences in the video. DOUBLE CLICK TO VIEW VIDEO.

JUST FOR FUN – When you have finished your webquest, click on this link – My Rollercoaster and design
your own rollercoaster. At the end, you will get a rating of “thumbs up” or “thumbs down”. Be sure to
click where at the end to read about the “goods and bads” of your rollercoaster. Rollercoaster are a good
example of Newton’s laws that you learned about above.
