PPT-CENTRAL FORCES General properties of Central Force

Central Force is Confined to a Plane If p is the linear momentum of a particle of mass µ the torque τ about an axis passing through the center of force is If the angular momentum L of mass . 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, . Maintaining Equilibrium or Changing Motion. PSE4U. Mr. MacMillan. Something to Think About. A gymnast maintains a position on one. foot during a balance beam routine. A . rock climber clings by her fingertips to. One popular urban myth tells a story of a man who makes a wish from the top of the Empire State Building, then tosses a penny off the roof. Over 1,000 feet below, a pedestrian is hit by the speeding penny and killed. …Good luck, huh?. 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. . 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. 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.. 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 . 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. . . 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 . The most important chapter of physics EVAR. What is a Force?. A force is a push or a pull. Contact forces:. Boat pulling a water skier. Pushing a car with a dead battery. Noncontact forces:. Gravitational attraction of moon to earth. 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.. What is a force?. A force is a push or a pull. . Forces make objects accelerate. What are the two general types of forces? How are they different?. Type 1: Contact Forces. Force as a result of object touching. WALT understand that a force is and what it does?. https://www.youtube.com/watch?v=LEs9J2IQIZY. https://www.bbc.com/bitesize/clips/zp4g9j6. https://www.bbc.co.uk/bitesize/clips/zch4wxs. https://www.bbc.co.uk/bitesize/topics/zvpp34j. Prof. D. M. Parshuramkar. Dept. Of Physics. N. H. College, Bramhapuri. Introduction :-. . Newton formulates his three law’s of motion which gave qualitative and quantitative measures of forces. Different types of forces actually arise in nature. Basically there are four fundamental types of forces depending upon the interaction of matter. There are following forces, .
