PPT-1. Forces & Motion Review (material so far)

2 Gravity Mrs Deeley 7th Grade Science 1 Review Motion is a change in position over time Motion is described in relation to a reference point Speed is the rate of motion Inertia . 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. . 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. . The Armed Forces Covenant Fund. The Covenant Fund - £10M per annum in perpetuity.. It has 4 broad funding themes now and in the future. . . Removing barriers to family life;. Extra support after service for those that need help; . 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. 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 . 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.. Science Question of the Day . What causes the noise when you crack your joints?. _________________________________. _________________________________. _________________________________. Gravity . Gravity is a specific kind of _____________.. 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 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 Force and Motion Basketball Review Game Game Rules If your team gets the question right, you get a chance to shoot the ball into the hoop. If you get the ball in the hoop, each person on your team wins a piece of candy. 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. .
