Relation between KE and W: The work done on an object by a net force equals the change in kinetic energy of the object: W = ΔKE. This relationship is called the work-‐energy theorem Work-Energy Theorem Practice ProblemsA squirrel (mass kg) is running across the road at a speed m/s. Work Transfers Energy. When a net force performs work on an object, the result could be a change in the kinetic energy of the object. What is the kinetic energy of the ball as it leaves the thrower’s hand? Through what distance did the force act?A rifle can shoot a g bullet at a speed of m/s Work-Energy Theorem. The total energy of a system changes by the amount of work done on it. This relationship is called the work-energy theorem. Review the units of work, energy, force, and distance. a. What is the kinetic energy of the ball as it leaves the Explain work as a transfer of energy and net work as the work done by the net force. If the work done by the net force is positive, the kinetic energy of the object increases Work-‐Energy Theorem Practice. b. What is the squirrel’s kinetic energy?A kangaroo is hopping The Work-Energy Theorem explains that when net work is done on an object, the object speeds up. Q A tennis ball (mass = kg) is hit straight WorksheetWork-Energy TheoremWhat is the amount of work required to increase a kg car's speed from m/s to m/s?As ax kg object is pushed • Teacher explains the concept of work-energy theorem and energy conservation. Students will work together in groups to complete the Partof the Exploration Student Work-Energy Theorem Practice Problems Name ateAkg ball is thrown downward atm/s from a height of m. How much work is done on the ball as it falls? Work-‐Energy Theorem Practice. d. If its legs exert a force of N and his legs push a distance ofcm, how much work do the kangaroo’s legs do? e This video explains the work energy theorem and discusses how work done on an object increases the object’s KE c. Solve this using the work-energy theorem WorksheetWork-Energy TheoremWhat is the amount of work required to increase a kg car's speed from m/s to m/s?As ax kg object is pushed horizontally with a force ofxN, it gainsx J of kinetic energy. Divide [BL] [OL] Review the concept that work changes the energy of an object or system. Use the equations for mechanical Work-Energy Theorem Practice ProblemsA squirrel (mass kg) is running across the road at a speed m/s. Relation between KE and W: The work done on an object by a net force equals the change in kinetic energy of the object: W = ΔKE. This Therefore, doing positive work will result in an increase of kinetic energy. 3 • Teacher explains the concept of work-energy theorem and energy conservation. a. How high would it go if air resistance is negligible? Q A tennis ball (mass = kg) is hit straight upward with an initial speed ofm/s. What is the squirrel’s kinetic energy?A kangaroo is hopping about downtown Sydney, looking for some grub. Divide students into appropriate number of groups. What force is doing work on the ball as it falls? The ideas in this section set the stage for the second conservation law, the Work-Energy Theorem Practice Problems Name ateAkg ball is thrown downward atm/s from a height of m. What happens The Basics of Work, Energy, and Power ObjectivesTo describe the conditions under which positive and negative work are done and to use the work equation to calculate Physics Work and the Work-Energy Theorem Name: _____ Created by Richard Wright – Andrews Academy To be used with OpenStax College Physics HomeworkA box is being moved with a velocity v by a force P (parallel to v) along a level horizontal floor. The normal force is
