What is Energy?
... 3. After the girl hits the ball, the ball moves very fast and has energy. When the ball hits the fielder’s glove, it stops moving. Given that energy can never be destroyed but merely changes form, what happened to the energy the ball once had? (Hint: If you are the fielder, what do you hear and feel ...

Chap3_energy
... Use the principle of conservation of energy to analyze events in which work and different forms of energy are transformed into one another. Discuss why heat is today regarded as a form of energy rather than as an actual substance. Define linear momentum and discuss its significance. Use the principl ...

Forms of Energy
... What are kinetic and potential energy? • You know that there are many forms of energy. But all forms of energy can be classified as potential or kinetic energy. • Kinetic energy is the energy of motion. • Do you think an object with more kinetic energy is moving faster or slower compared to an obje ...

Chapter 4 Work and Energy
... a)Before the object started falling ME = PE, so ME = 480.0J. b)As the object is falling PE is being converted to KE. c)At anytime during the fall ME = PE + KE. d)When the object is two-thirds of the way down ME = 1/3PE + 2/3KE. e)So: KE = 2/3(480.0 J), or KE = 320.0J ...
