Edexcel International GCSE J anuary 201 5 Understanding our Edexcel International GCSE grade boundaries This document shows the grade boundaries for our suite of Edexcel International GCSE qualifi 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 . 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.. Topic VII . Division of Science . Benchmarks. SC.2.P.13.1 . Investigate the effect of applying various pushes and pulls on different objects. . Cognitive Complexity. : Level 3: Strategic Thinking & Complex . What is a force?. A force is a push or a pull. . Forces make objects accelerate. What are the two general types of forces? How are they different?. Type 1: Contact Forces. Force as a result of object touching. Science Question of the Day . What causes the noise when you crack your joints?. _________________________________. _________________________________. _________________________________. Gravity .

Of Mice and Men. A: Character. B: Language. C: Other part of the novel plus context. Science Question of the Day . What causes the noise when you crack your joints?. Gravity . Gravity is a specific kind of force.. A force is simply the push or a pull on an object.. Can you think of some examples of pushes and pulls on objects?. 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 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. . 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. . Review: Forces. What is a force? . Why do you think it’s important to learn about forces? What about gravity and friction?. How might an understanding of forces help you in your everyday life? .
