PPT-Forces In Motion

Part II RED SLIDE These are notes that are very important and should be recorded in your science journal Copyright 2010 Ryan P Murphy Nice neat notes that are legible and use indentations when appropriate Example of indent Skip a line between topics Make visuals clear and well drawn Please label . Forces act on you all the time. . If . you surf, you can feel many forces pushing and pulling you in different directions. . Gravity . always pulls you down, towards planet Earth. . This . force can be balanced by the support of the surfboard acting upwards. . 11.1: Forces change motion. 11.2: Force and mass determine acceleration. 11.3 Forces act in pairs. 11.4 Forces transfer momentum. Warm-up Questions (T or F). Speed includes direction, while velocity does not. 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 . Robert Strawn. Compiled 10/16/11. A force is any push or pull that one object exerts on . another that causes a change in motion, direction, or shape.. The unit for force is the Newton (N) and is equal to . Housekeeping. Newton’s . First Law of . Motion. Newton’s Second Law of . Motion. Newton’s Third Law of Motion. Glossary. Inertia. is the property of objects that makes them resist changes in their motion. So, the greater the mass of an object, the more inertia it has. For example, it takes a much . Forces felt in . - and . -fields. Motion of particle in a . -field. Applications.  . Charges set up an . electric field . , in which other charges feel an . electric force. Currents (or magnets) set up a . Can cause a change in the motion of an object.. Tug-of-War Example:. . In the pictures above, each person is pulling with a force of 50N (. N. ewtons. ).. What will happen when the person from the first picture drops out?. Student notes are shown in blue.. Force Defined. Any influence that can cause a change in an object’s motion.. A bat strikes the ball with a force that causes the ball to stop and then move in the opposite direction.. 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. . . Example:. What is a force? . a) Strong . nuclear . force. b) Electromagnetic force. c) Weak force. d) Gravity.. EXAMPLE? an atom . #2) There are four forces that hold all matter together. 3) Gravitational forces . 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. 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.. Dynamics I Forces & Newton’s First Law 4 Natural Forces Gravity : acts between all masses in the universe and has “infinite” range Electromagnetic (EM) Force : acts between electrically charged particles and “magnetically charged” poles . Scalars and vectors. . Types of forces. . Resultant of forces. . Equilibrium of particles. Scalar and Vectors. . Scalar - . a physical quantity that is completely described by a real number.
