PPT-Forces and Motion Project

By MEHERET ZELALEM Sport Rugby Also rugby Also called rugger Rugby football A form of football played between 2 teams of 15 members each that differs from soccer in freedom to carry the ball block with the hands and arms and tackle and is characterized chiefly by continuous action and prohibition against the use of substitute players. 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. . Here’s Tim & Mobey on Force. Brainpop. Suppose I asked you to move a heavy desk in the classroom. How would you move it? . hmmmmmmmmmmm...... You might get on one side of the desk and start pushing, Or you might grab the legs and start pulling. . 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. A force is a push or a pull on an object. Every force has strength, magnitude and direction.. Forces acting on a stationary object can set the object in motion. . They can also change the object’s speed or the direction it is moving in.. 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. . 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.. 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. EDEXCEL TOPIC 2 - MOTION AND FORCES (part 1) Describing Motion Average speed = distance ÷ time s = d ÷ t Speed Metre/second ( m/s) Distance Metre (m) Time Second (s) Current Ampere (A) Temperature 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? . 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. .
