14 explain the relationship between work and power using narrative and mathematical descriptions and apply to realistic situations GPS HSGT SCPHC200514 14a calculate the work on a body by constant force. In text: Ch 5. Do you already know these words?. Work – . Energy – . Power – . 2.3.1 Outline . what is meant by work.. First a demo:. One volunteer. Hold a couple of books and walk across the room.. 8, . 2016. Learning target: I can define work in terms of force and displacement. Vocabulary: mechanical energy . kinetic energy potential energy. Go over homework . 3 . and 4 sheet, . practice . Chapter 14 Section 3. Mechanical Advantage. The . mechanical advantage. of a machine is the number of times that the machine increases an input force. Suppose a nut is in a nutcracker at position A . Work . = W. The product of the force . F . applied to an object over a distance . d . in which the object travels as a result of the force. Joule . (J) . is the base unit of work. (Force and distance must be parallel to each other). Energy. The capacity of vigorous activity. The ability to act. The capacity of a body or a system to do work (and heat). . . Mechanical . Energy: Kinetic . + Potential. h. Use directly for hydro . energy storage . IPC Spring . 2014.

Work Work transfer of energy through motion force exerted through a distance W = Fd Distance must be in direction of force! W : work (J) F : force (N) d : distance (m) Work, Power & Energy Work Work is the product of force and distance For a force to do work on an object, some of the force must act in the same direction as the object moves. If there is no movement, no work is done. OBJ. : . Students will determine relationships among force, mass, and motion.. OBJ. : . Calculate amounts of work and mechanical advantage using simple machines.. Work. When a force causes an object to move – work is done..
