PPT-Chapter 4 The Laws of Motion

Gravity Gravity Theres a lot about you thats attractive At this very moment you are exerting an attractive force on everything around you Your desk your classmates even planets millions of kilometers away. And 57375en 57375ere Were None meets the standard for Range of Reading and Level of Text Complexity for grade 8 Its structure pacing and universal appeal make it an appropriate reading choice for reluctant readers 57375e book also o57373ers students In Massachusetts those laws are set forth in a complex statutory framework that can be difficult to interpret and that causes much confusion among employ ers Among the questions that employ ers struggle with are Can I open on Sunday Do I need to pro Background information: what students needed to know. How to calculate velocity. Newton’s 3 Laws of Motion. Kinetic and static friction. Momentum. Making sketches. EDP steps . As engineers for a toy manufacturing company, students were expected to:. Kinematics Terminology. Scalar vs. Vector. Scalar: . quantities that have only a size, but no direction. i. e. : . distance, speed. Vector: . quantities that have a size and direction. ie. : . displacement, velocity. Forces. Forces can be thought of as pushes and pulls. Examples. You exert a force on a door to open it (a push). Gravity exerts a force on you which holds you to the surface of the earth (a pull). Forces. Examples:. Pendulum.. Oscillating spring (either horizontal or vertical) without friction.. Point on a wheel when viewed from above in plane of wheel.. Physics Classroom has a good lesson on simple harmonic motion under Waves, vibrations.. © 2016 Pearson Education, Inc.. Goals for Chapter 9 . To study angular velocity and angular acceleration.. To examine rotation with constant angular acceleration.. To understand the relationship between linear and angular quantities.. Standards. SPS8. Students will determine relationships among force, mass and motion. b. Apply Newton’s three laws to everyday situations by explaining the following:. Inertia. Relationship between force, mass and acceleration. Bormann. Honors Science - 8. Lets make some connections…. Aristotle – (384-322 BC). Nicolaus. Copernicus (1473-1543). Tycho. Brahe (1546-1601). Johannes . Kepler. (1571-1630). Galileo . Galilei. . Motion. Speed & Velocity. Acceleration. Newton’s First Law. Newton’s First Law of Motion. An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by a net force.. Newton’s First Law. Lesson 2. 1. . What causes an object in motion to remain in motion?. friction . inertia. gravity . velocity. 1. . What causes an object in motion to remain in motion?. Forces and Uniform Circular Motion Physics Unit 2 This Slideshow was developed to accompany the textbook OpenStax Physics Available for free at https:// openstaxcollege.org/textbooks/college-physics the . process of moving . or . changing . places . or position. Anything you do while moving is motion.. Fact: Speed is a major type of Motion. Determining motion. In order to determine motion you must know direction and speed. Describing motion is occasionally difficult to do with words. Graphs can help simplify this description greatly. Position = Distance from a starting point. Velocity = rate of change in position. Acceleration = rate of change in velocity.
