Write your answers on your own paper. 1. Define speed, force, inertia, gravity, and acceleration. 2. What are the 4 types of friction? 3. What does friction do? 4. How is weight determined? What makes it different from mass? 5. What is Newton's 1st Law? Give an example. 6. What is the difference in a balanced and unbalanced force? 7. What is the 2nd Law of Motion? Give an example. 8. How does mass and force affect acceleration? 9. How is mass, force, and acceleration related? 10. What is Newton's 3rd Law of Motion? Give an example. 11. How is friction useful? 12. How is gravity related to the 2nd Law of Motion? If you have not watched the videos on Google Classroom, please do so. I also have link below to some videos and review questions. Please click through, watch, and study!

Newton's 1st Law states that an object in motion stays in motion and an object at rest stays at rest until acted on by a force. Newton's 2nd law has to do with force, acceleration, and mass. It really means that if you increase mass then acceleration will decrease (of course because it weighted down) and if you increase force, acceleration will increase. They are all related in a formula: Force=mass x acceleration. An example would be if a pitch a baseball it will go faster than if I tossed it gently because I put more force behind the pitch! Also, heavier things require more force to accelerate like the illustration below.                       Newton's 3rd law says that for every action there is an equal and opposite reaction. The best example of this is a rocket launch. The gases combust out the bottom of the rocket and in turn the rocket gets pushed up in air. Equal and opposite forces!                       

I've found a way to post the chapters from the book we use in class to Google Classroom. I put Chapter 24 up today in the 'About' section. The students can use it to study this weekend! I will continue to post the chapters we use in future units, but they must also continue to study all classwork, activities, and notes since the questions don't all come from the material in the book. I'm glad we can have this resource since I am unable to send a book home with each student.
