PPT-World’s Best Work Force (WBWF) and what does it mean for

Nova Classical Academy Eric Williams Executive Director October 6 2016 Nova Classical Academy Goals        Outline key components of Worlds Best Work Force WBWF legislation . What do the F and d stand for?. What are the units for F and d?. What do the W and t stand for?. What is the unit for t?. Work is a form of energy. What is the unit for work and energy?.  . Work and Power. th. floor with an acceleration of 0.629 m/s. 2 . . As the elevator goes downwards, the acceleration of the elevator is 0.232m/s. 2. . Philip, who weighs 150. lbs, stands on a bathroom scale in this elevator. . Objectives: . Define mechanical work.. Calculate the work done in various situations.. . Work = . Fcos. d. Defining work. The Three Requirements. for Work: . Force, displacement, and cause. Physics. Trigonometry. Here are some diagrams to help you with the trigonometry. Try to figure it out yourselves before you ask for help. . Trigonometry. Good so call it: . G. Bad so call it: . W = Fd. Units and Direction. Positive and Negative Work. When Work = 0. Work. Work . (. W) is the . energy transferred to an object when a force acting on the object moves it through a distance . W = F x d. Work is the product of the force on an object and the distance through which the object is moved: the quantity . force . ×. distance. Work. If the force is constant and the motion takes place in a straight line in the direction of the force, the work done on an object by a net force is the product of the force and the distance through which the object is moved.. Work is done when:. A . force . is exerted on an object. An object has a . displacement . in the same direction as the force. W=. Fdcos. q. SI unit for work is . Joule . (. J. ). 1 J = 1N*m (=0.7376 . You exert force on a pencil when you write. Forces are described by how strong they are and in what direction they are going. vocabulary. word!. Unbalanced Forces. unbalanced forces . - . will . change the object’s motion. You exert force on a pencil when you write. Forces are described by how strong they are and in what direction they are going. Unbalanced Forces. Unbalanced forces on an object will change the object’s motion. If it takes you 5 seconds to move the desk, how much power do you produce?. Place answers on a note card and place the note card in the fish bowl!. To help rearrange the furniture in your classroom, you exert a force of 20 N to push a desk 10 m. How much work do you do?. Lesson 5.1 Work Essential Question: How do you calculate work? Which situation is an example of work? Holding a set of exercise weights up in the air Pushing your car down the street because it ran out of gas Work. Force applied across a distance.. Work Lab. Work Equation. W = . Fd. (N)(m) = Nm Newton meter. 1 Nm = 1 J. (Work and energy are like sisters. It takes energy to do the work. Work is what you do. Energy is what you use).. Vocab. Energy – the ability to do work or cause change. Motion – an object’s position changes relative to another object. Force – a push or pull. Work – when the force exerted is in the same direction as the motion. You probably think of…. In physics…. Work. is performed when a force that is applied to an object moves that object.. When is work done?. The . force and motion . of the object have to be in the .
