PPT-Unit 5: Force and Motion

Week 2 102615 103015 Learning Targets Monday October 26 2015 I can identify a force I can demonstrate forces acting on an object I can demonstrate how unbalanced forces change the direction of an objects motion. Chapter 2 Section 2 Review. A. . An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.. B. . Every action has an equal and opposite reaction. . 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?. 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 . 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?. Frame of reference- . a system of objects that are not moving with respect to another.. Also called a . Point of Reference. - Describing and Measuring Motion. Describing Motion. Whether or not an object is in motion depends on the reference point you choose. Can you change your velocity while not changing your speed?. v. F. Consider the above situation.. According to Newton . S. econd law, what must the object be doing?. It is accelerating so the velocity must be changing.. Physics. Coach Taylor. Broad Run High School 2010-2011. Objectives. Recognize that the vertical and horizontal motions of a projectile are independent.. Relate the height, time in the air, and initial vertical velocity of a projectile using its vertical motion, then determine the range.. Uniform Circular motion. For an object moving on a circle at constant speed. The . speed is constant. , but the . direction is not. Acceleration is a change in velocity, but speed is constant. The change in velocity is only in its direction. 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. © 2016 Pearson Education Inc.. Learning Goals for Chapter 14. D. escribe oscillations in terms of . amplitude. , . period. , . frequency. , & . angular frequency. .. A. pply . simple. . harmonic. 1. Changing Units. Speed of a car is 80 miles/hour. What is it in m/s. Multiply by 1 so units cancel and correct units are left. In units of m/s: {80 miles * (5280 feet/mile)*(1 m/3.28 feet)}/hour. 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. Vocab. Energy – the ability to do work or cause change. Motion – an object’s position changes relative to another object. Force – a push or pull. Work – when the force exerted is in the same direction as the motion.
