and Momentum Revision Mock 2015 Stopping distances Thinking distance is the distance a car travels before the brakes are applied Braking distance is the distance a car travels whilst the brakes are being applied. 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. 11.1 States of Matter . . . Kinetic Molecular Theory . 11.7 Pressure. States of Matter. T. hree common states of matter. Solid. Liquid. G. as. Differences . between . states . can be explained by considering the . 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 . 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. . . . 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. the forces between (among) individual particles (atoms, ions, molecules); they are weak relative to . intramolecular. forces (i.e. covalent and ionic bonds within a compound). Intermolecular forces are increasingly significant in this order:. 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 . Gravity is a specific kind of _____________.. 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?. 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. . 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. The Covenant sets out the relationship between the nation, the government and the Armed Forces. It recognises that the whole nation has a moral obligation to members of the Armed Forces and their families, and it establishes how they should expect to be treated. .
