PPT-Topic 1 Lesson 1 6 th Grade: energy, motion, force, and work

Vocab Energy the ability to do work or cause change Motion an objects position changes relative to another object Force a push or pull Work when the force exerted is in the same direction as the motion. Discuss native speaker pronunciation gonna Stress that they dont have to do it but they need to be able to understand it Use selected items from textbook exercises for student practice and to identify and clear up any confusion Strategy Presentation Grade 2. What is energy?. Energy . is the ability to do work. . Energy can cause things to move. . There are different types of energy such as light, heat, sound, and motion.. We store energy from food in our bodies.. Newton’s Laws. Isaac Newton. The man, myth, the legend…while you spend your time on Facebook, Newton spent his studying the behavior of objects in MOTION.. His conclusion…anything in motion is going to follow 1 of the 3 basic . STability. Chapter 3 . Movement Principles can be applied to a variety of movements to improve performance. Sir Isaac Newton’s 3 Laws of Motion. (inertia) An object at rest . stays at rest. , and an object in motion . Central Force is Confined to a Plane. If p is the linear momentum of a particle of mass . µ. , the torque . τ. about an axis passing through the center of force is :. If the angular momentum L of mass . U2L2. 2. Lesson 2 Key Question. Example: Consider giving a low-friction cart a quick shove along a track.. When an object is moving, does this mean there must be a force pushing it in the direction of its motion?. Nature of science: . Observations: The ideas of motion are fundamental to many areas of physics, providing a link to the consideration of forces and their implication. The kinematic equations for uniform acceleration were developed through careful observations of the natural world.. Work is done when:. A . force . is exerted on an object. An object has a . displacement . in the same direction as the force. W=. Fdcos. q. SI unit for work is . Joule . (. J. ). 1 J = 1N*m (=0.7376 . © 2016 Pearson Education Inc.. Learning Goals for Chapter 14. D. escribe oscillations in terms of . amplitude. , . period. , . frequency. , & . angular frequency. .. A. pply . simple. . harmonic. Dynamics is the study of force and its effect of motion.. A force is a push or pull that can change the inertia of an object.. Newton’s First Law of Motion. Every body continues in its state of rest or motion, unless acted upon by a force.. Work, Power & Energy Work Work is the product of force and distance For a force to do work on an object, some of the force must act in the same direction as the object moves. If there is no movement, no work is done. Lesson 5.1 Work Essential Question: How do you calculate work? Which situation is an example of work? Holding a set of exercise weights up in the air Pushing your car down the street because it ran out of gas 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. Why not?. Does energy just disappear? No!. Law of Conservation of Energy. : energy cannot be created nor destroyed.. -energy can change forms. 1. st. Law of Thermodynamics. : energy can do work, or produce heat, but it is always conserved..
