1) The 17th century scientist who studied force and motion was Sir Isaac Newton.

TRUE or FALSE

TRUE

1) Newton’s first law applies when forces are balanced.

TRUE or FALSE

TRUE Objects will remain in motion or at rest until a force acts upon them.

1) Newton’s second law is often expressed as the formula E = mc2.

TRUE or FALSE

FALSE Newton’s second law states: F = m*a Force = mass * acceleration

1) Newton’s second law applies any time you’re trying to accelerate an

• bject.

TRUE or FALSE

TRUE F = m * a To change acceleration, you must consider force and mass.

1) The more mass an object has, the less force is needed to accelerate it.

TRUE or FALSE

FALSE F = m * a To move more mass, you need more force.

1) Newton’s third law says: “For every action, there is an equal and

• pposite reaction.”

TRUE or FALSE

TRUE

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 or FALSE

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.

1) The resistance of an object to a change in motion is called inertia.

TRUE or FALSE

TRUE Newton’s first law is called, “The Law of Inertia”

1) Inertia is the tendency of an object to stop when there are no forces on it.

TRUE or FALSE

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.

1) All objects have momentum when they’re in motion.

TRUE or FALSE

TRUE Momentum = mass * velocity P = m*v

1) A force is a push or pull on an object that results from its interaction with another object.

TRUE or FALSE

TRUE

1) Only large objects with a lot of mass have gravity.

TRUE or FALSE

FALSE Anything with mass has gravity.

1) Acceleration is a change in velocity.

TRUE or FALSE

TRUE When forces are unbalanced, an object will change speed and/or direction.

1) Velocity is an object’s speed and mass.

TRUE or FALSE

FALSE Velocity is a speed and direction.

1) The combined effect of all forces acting on an object is the motion force.

TRUE or FALSE

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.”

Newton’s Laws Video

1) Read Chapter 11.1 (pg. 345).

a) Answer questions 1-6 (pg. 351). Write the full question and a complete answer.

2) Create a pamphlet on Newton’s 3 laws.

a) See examples on table up front. b) Be careful with markers, they bleed through. 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.

Studying Newton’s Laws

While working:

• Headphones OK
• Voice level 1 OK
• Do not change seats without teacher

permission.

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 1st law. d) Time to work on chapter 11 and Newton pamphlet. Wednesday, 4.10.2019

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.

What is close reading?

By marking text in a specific way, you train yourself to find important parts

• f 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.

Close Reading Process: Marking the text

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 1st law. c) Finish textbook 11.1 (due tomorrow) d) Work on Newton’s laws pamphlet (due Tuesday) Thursday, 4.11.2019
