PPT-E06 Motion & Forces

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. EQ: What causes an object’s motion to change?. A . hard kick sends a soccer ball shooting down the field toward a goal.. Just in time, the goalie leaps forward, stops the ball, and quickly kicks it in the opposite direction.. 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. . 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.. 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 . 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.. . . 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 . 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 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. 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. .
