TRUE or FALSE 1) The 17th century scientist who studied force and motion was Sir Isaac Newton. TRUE
TRUE or FALSE 1) Newton’s first law applies when forces are balanced. TRUE Objects will remain in motion or at rest until a force acts upon them.
TRUE or FALSE 1) Newton’s second law is often expressed as the formula E = mc 2 . FALSE Newton’s second law states: F = m*a Force = mass * acceleration
TRUE or FALSE 1) Newton’s second law applies any time you’re trying to accelerate an object. TRUE F = m * a To change acceleration, you must consider force and mass.
TRUE or FALSE 1) The more mass an object has, the less force is needed to accelerate it. FALSE F = m * a To move more mass, you need more force.
TRUE or FALSE 1) Newton’s third law says: “For every action, there is an equal and opposite reaction.” TRUE
TRUE or FALSE 1) Once an object is moving, it doesn’t need a force to keep it moving; it needs a force to make it stop moving. TRUE Newton’s first law: An object in motion will remain in motion until it is acted upon by an outside force. If something is moving, it will keep moving unless something stops it.
TRUE or FALSE 1) The resistance of an object to a change in motion is called inertia. TRUE Newton’s first law is called, “The Law of Inertia”
TRUE or FALSE 1) Inertia is the tendency of an object to stop when there are no forces on it. FALSE Newton’s first law: An object in motion will remain in motion until it is acted upon by an outside force. If something is moving, it will keep moving unless something stops it.
TRUE or FALSE 1) All objects have momentum when they’re in motion. TRUE Momentum = mass * velocity P = m*v
TRUE or FALSE 1) A force is a push or pull on an object that results from its interaction with another object. TRUE
TRUE or FALSE 1) Only large objects with a lot of mass have gravity. FALSE Anything with mass has gravity.
TRUE or FALSE 1) Acceleration is a change in velocity. TRUE When forces are unbalanced, an object will change speed and/or direction.
TRUE or FALSE 1) Velocity is an object’s speed and mass. FALSE Velocity is a speed and direction .
TRUE or FALSE 1) The combined effect of all forces acting on an object is the motion force. FALSE The combined effect is called the net force.
SIR ISAAC NEWTON Isaac Newton was a mathematician, philosopher, and physicist. He lived from 1642 – 1727 (84yrs) During England’s Commonwealth and Restoration Periods. Developed Calculus, the Theory of Universal Gravity, and Newton’s Laws of Motion. Considered by many to be, “the smartest person who ever lived.”

Tuesday, 4.9.2019 1) Please turn in any missing work and be ready for class: a) Notebook paper b) Pencil c) Textbook 2) Today’s Plan: a) Intro video b) Chapter 11.1 c) Newton’s laws pamphlet
Newton’s Laws Video - Isaac Newton’s Laws from Physics in Motion on PBS - https://www.pbs.org/video/newtons-laws-overview-cfqmjz/
Studying Newton’s Laws 1) Read Chapter 11.1 (pg. 345). a) Answer questions 1-6 (pg. 351). Write the full question and a complete answer. While working: 2) Create a pamphlet on Newton’s 3 laws. - Headphones OK a) See examples on table up front. - Voice level 1 OK b) Be careful with markers, they bleed through. - Do not change seats without teacher permission. c) Each section must include: 1) The full law, copied from textbook glossary (Pg. R63 in back). 2) A “simple version” of the law, written in your own words. 3) The common name of the law (Law of Inertia, etc.). 4) A diagram. 5) An example of the law in action. 3) If you finish: Explore the PhET demos in the SCIENCE! Portal.
Wednesday, 4.10.2019 1) Turn in any completed work. 2) Pick up a self-starter sheet. This is set #6. 3) Self-Starter #1 a) 1.1 – 1.3: List Isaac Newton’s 3 laws of motion. 4) Today’s Plan: a) Self-Starter b) Questions from Tuesday. c) Close reading exercise on Newton’s 1 st law. d) Time to work on chapter 11 and Newton pamphlet.
What is close reading? Close reading makes reading much more effective and useful. Close reading skills help you: 1) Understand difficult text more easily. 2) Identify important ideas and concepts in the reading. 3) Remember what you read. We will practice close reading skills with an article on Newton’s first law.
Close Reading Process: Marking the text By marking text in a specific way, you train yourself to find important parts of the reading. Step 1) Number the paragraphs on the left side. -This helps us refer to paragraphs when we talk about the text. Step 2) Circle key words and terms. -Words or phrases you don’t know or you think others won’t know, and specific vocabulary. Step 3) Underline supporting information - Claims by the author, supporting evidence, main ideas, explanations.
Thursday, 4.11.2019 1) Turn in any completed work. 2) Self-Starter #2 2.1) In this comic, wh0 is the man on the right? 2.2) TRUE or FALSE: Friction is a force. 2.3) TRUE or FALSE: If something is moving, the forces on it must be unbalanced. 3) Today’s Plan: a) Self-Starter b) Finish close reading exercise on Newton’s 1 st law. c) Finish textbook 11.1 (due tomorrow) d) Work on Newton’s laws pamphlet (due Tuesday)
