State the law of conservation of energy. Energy cannot be created or destroyed, only transferred from one store to another. An apple in a tree has a gravitational store of 10 J. As it falls, it accelerates constantly until it hits the ground. What is the apple’s maximum kinetic store? The maximum kinetic energy is 10 J. 2.
Worksheet #8: Conservation of Mechanical Energy Student Name: Energy (E) is defined as the capacity to do work (scalar). The unit for all energy and work is the Joule Mechanical energy- the energy due to the position of something or the movement of something.
Law of Conservation of Energy Practice Worksheet. Answer the following questions and show your work! 1. Consider this ball rolling down a hill. Fill in the missing energy amounts. 2. Consider this basketball that has a mass of 0.6 kg. If it has 12 J at the top, what is the height? (at the top) PE= 12 J, KE = ________
What is its total mechanical energy? (mechanical energy includes kinetic, gravitational potential, and elastic potential but not internal forms of energy such as thermal or chemical)
Calculate the kinetic energy of a 750 kg compact car moving at 50 m/s. Determine the mechanical energy of a 450 kg roller coaster moving at 30 m/s at the bottom of the first dip which is 15 meters above the ground. Julie has a mass of 49 kg.
