PPT-Science 8 Chapter 2-The Laws of Motion

Newtons 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. What is a scientific theory?. . a well-supported explanation about the natural world.. . What does it really mean?. A scientific theory . EXPLAINS . WHY or HOW something happens.. Example 1:. The Big Bang Theory . 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:. MODELS. Shuftan. Process. The image of a miniature model is reflected into the camera via a mirror.. Where the image of the miniature is not desired, that portion of the mirror silvering is scraped away, allowing the camera to see through the clear glass and photograph the primary scene, which is usually the foreground and live action.. Simple version of Newton’s three laws of motion. Newton’s Laws and the Mousetrap Racecar. 3. rd. Law: “for every action there is an equal and opposite reaction”. Is more mass a good thing or a bad thing for a mousetrap racecar to go far?. 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. & Providing Order to the Universe . Methods of Science. Explanation in Science. Science and Pseudoscience. The Ordered Universe. Geocentric Universe. Heliocentric Universe. Newton’s Laws and the Founding of . Science is a systematic enterprise that builds and . organizes . knowledge in the form of testable explanations and predictions about the universe. .. What is Science?. Formal – logic and mathematics. 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. Changes in Motion. Objectives:. 1. Describe how force affects the motion of an object.. 2. Interpret and construct free-body diagrams.. The Force is Strong With You. Force. is an action exerted on an object which may change the object's state of rest or motion.. Forces. We have learned that forces . either pushes or pulls.. They come in many varieties:. Gravity & Normal. Kinetic & Static Friction. Electrical & Magnetic. Air resistance. Tension. Nuclear Force. Rules and regulations made and enforced by government that regulate conduct within a society. Jurisprudence- the study of law and legal philosophy. Home, School, Outside World. Without law there would be confusion and disorder.
