Review Ideas about Friction What is friction and how does it work Are there bumps anywhere else besides the surface an object moves across Give an example of friction from your everyday life . Newton’s Laws. B. rought to you by: Sir Isaac Newton and . Laura . Akesson. (mostly Newton). NASA for Educators. nasa.gov. For Educators. Find Teaching Materials. scienceoverdrive.org. Newton’s First Law of Motion. These are the slides that I intended to show in class on Wed. Jan. 16, 2013. . They contain important ideas and questions from your reading. . Due to time constraints, I was probably not able to show all the slides during class. . On a post-it, write down anything you know about the word force or the different ways you use the word force.. Scientific Definition. A force is a . push . or a . pull. of an object.. When there is a force, one object is applying a force and on object is receiving the force.. Interaction forces. Forces arise from an interaction between two objects. They come up in pairs. Each force in an interaction pair acts on a different object. The forces are equal in size and opposite in direction. Grade 2. What is energy?. Energy . is the ability to do work. . Energy can cause things to move. . There are different types of energy such as light, heat, sound, and motion.. We store energy from food in our bodies.. 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 . . Physics. Story Time:. “HOW I FINALLY TAUGHT THE BIG GUY A LESSON.”. In Words:. EVERY action has an EQUAL and OPPOSITE reaction. .. (Equal in magnitude/number, opposite in direction.) . ALL forces. pairs. , one on . each object. in the pair. . The magnitudes of the forces in a pair are always ________, and the direction is . _____________. . (They do not cancel each other…because they are on . 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 types of forces . do you already know?. Different types of forces . Forces are usually divided into . two . types. . . C. ontact . forces. . occur . because of physical contact between objects. . Force. - a . push. or . pull . A . Force . 1. gives. . energy . to objects. 2. causes a. . change . in motion, such as:. . Starting. Speeding Up. Changing Direction. Stopping. Slowing Down. (Note: all of these are forms of . Newton’s First Law. Lesson 2. 1. . What causes an object in motion to remain in motion?. friction . inertia. gravity . velocity. 1. . What causes an object in motion to remain in motion?. Newton. The measurement of force. *You can measure force using the spring scale at a grocery store.. *A force is measured in . newtons. .. *one newton is equal to one kilogram meter per second squared.
