PPT-Force and Motion–I

Chapter 5 Copyright 2014 John Wiley amp Sons Inc All rights reserved Goals for this chapter 2014 John Wiley amp Sons Inc All rights reserved To understand the meaning of force . Chapter 2 Section 2 Review. A. . An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.. B. . Every action has an equal and opposite reaction. . express angular displacement in radians. . understand and use the concept of angular velocity to solve problems. . recall and use . v = r. ω. to solve problems. . describe qualitatively motion in a curved path due to a perpendicular force, and understand the centripetal acceleration in the case of uniform motion in a circle. . 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. . STability. Chapter 3 . Movement Principles can be applied to a variety of movements to improve performance. Sir Isaac Newton’s 3 Laws of Motion. (inertia) An object at rest . stays at rest. , and an object in motion . U2L2. 2. Lesson 2 Key Question. Example: Consider giving a low-friction cart a quick shove along a track.. When an object is moving, does this mean there must be a force pushing it in the direction of its motion?. 1. A system of objects that are not moving with respect to one another. Used to determine the motion of an object.. Frame of Reference. 2. If you were measuring the length of a lunch tray you would most likely label it with the following unit.. What is motion?. Motion . is . when an object changes its . position. .. Motion . can be represented mathematically through calculations of . speed, velocity, and . acceleration. Motion is . when an object changes its position. Forces. We have learned that forces . either pushes or pulls.. They come in many varieties:. Gravity & Normal. Kinetic & Static Friction. Electrical & Magnetic. Air resistance. Tension. Nuclear Force. Using 9 boxes, create a comic strip that explains the relationship between force and motion. The comic strip must include the following: . Creative. dialogue. between 2 characters (of your choice) that includes the following vocabulary: . Dynamics is the study of force and its effect of motion.. A force is a push or pull that can change the inertia of an object.. Newton’s First Law of Motion. Every body continues in its state of rest or motion, unless acted upon by a force.. Ryan Cates. University of South Florida. Big Idea 11: . Energy . Transfer and Transformation. Vocabulary Review. What is a force?. Why do weights differ on other planets?. What is the difference between mass and weight?. 1. Changing Units. Speed of a car is 80 miles/hour. What is it in m/s. Multiply by 1 so units cancel and correct units are left. In units of m/s: {80 miles * (5280 feet/mile)*(1 m/3.28 feet)}/hour. 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?. 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?.
