PPT-Unit F: Chapter One Forces and Motion

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. Definition: . A . force. is a push or a pull in a particular direction.. How does it balance?. Textbook p. 53. You probably would be uneasy standing under Balanced Rock near Buhl, Idaho. Yet this unusual rock stays in place year after year. The rock has forces acting on it. So, . 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. Week 2. 10/26/15 – 10/30/15. Learning Targets. Monday, October 26, 2015. I can identify a force.. I can demonstrate forces acting on an object.. I can demonstrate how unbalanced forces change the direction of an object’s motion.. Book Section 10.2. Simple Harmonic Motion. Also called . vibrational motion. , . oscillation. , or . periodic motion. .. Think springs, pendulums, atoms carrying sound, or buildings or trees swaying in the wind.. Forces. Forces can be thought of as pushes and pulls. Examples. You exert a force on a door to open it (a push). Gravity exerts a force on you which holds you to the surface of the earth (a pull). Forces. 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. . Define . forces and different types of forces (push or pull). Measuring . forces in Newtons. Balanced . vs unbalanced forces. Inertia- . what is it and how does it apply to Newton’s first law of motion.. 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. select . “View”. on the menu bar and click on . “Slide Show.”. . To advance through the presentation, click the right-arrow key or the space bar.. From the resources slide, click on any resource to see a presentation for that resource.. 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..

Forces and Uniform Circular Motion Physics Unit 2 This Slideshow was developed to accompany the textbook OpenStax Physics Available for free at https:// openstaxcollege.org/textbooks/college-physics . 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? .
