Work and energy quizlet. The following concepts are emphasized. If a man is pushing a wheelbarrow up a hill describe what is occurring in terms of energy when the man is half way up the hill. A man stops his car on top of a hill describe this scenario in terms of energy.
Questions pertain to the analysis of motion using relationships related to work and energy mainly energy conservation and work-energy transfer principles. 1 2 mv i 2 mgh i 1 2 kx i 2 1 2 mv f 2 mgh f 1 2 kx f 2 18. When the pencil reaches the ground all the energy is kinetic energy.
A push or a pull exerted on an object in order to change the motion of the object. Physics 2 Online Quiz 2. How much Work is done in lifting a 200N block a vertical Distance of 25m.
Energy causes a change and work is needed for energy to happen. Weighing machines of all sorts employ springs that take a certain amount of force to keep compressed or stretched to a certain point. The work done on an object by a constant force F as FΔxcosθ where F is the magnitude of the force Δx the magnitude of the displacement and θ the angle between the displacement.
