PPT-Force and Motion: Part ii

Ryan Cates University of South Florida Big Idea 11 Energy Transfer and Transformation Vocabulary Review What is a force Why do weights differ on other planets What is the difference between mass and weight. A projectile is an object upon which the only force acting is gravity. .. An . object dropped from rest is a projectile (provided that the influence of air resistance is negligible). .  . An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). . 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?. Book Section 10.2. Simple Harmonic Motion. Also called . vibrational motion. , . oscillation. , or . periodic motion. .. Think springs, pendulums, atoms carrying sound, or buildings or trees swaying in the wind.. Forces. Forces. Forces have . Magnitude . and . Direction. . We represent these in diagrams with arrows. . Larger the force the bigger the arrow. . 50N in Each direction. Forces and Motion. When we look at a diagram we can figure out the sum of forces. . 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?. 1. A system of objects that are not moving with respect to one another. Used to determine the motion of an object.. Frame of Reference. 2. If you were measuring the length of a lunch tray you would most likely label it with the following unit.. Material on Final Exam. Section 1: Measuring Motion. Objectives:. Describe the motion of an object by the position of the object in relation to a reference point. Identify the two factors that determine speed. You exert force on a pencil when you write. Forces are described by how strong they are and in what direction they are going. vocabulary. word!. Unbalanced Forces. unbalanced forces . - . will . change the object’s motion. 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. © 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.. 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?. 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.
