Imagine a book that is falling from a shelf. At a particular moment during its fall, the book has a kinetic energy of 25 J.
What was the initial potential energy of the book, and what is its total kinetic energy at the instant just before it strikes the floor?

Kate is working on a project in her tech education class. she plans to assemble a fan motor. which form of energy does the motor convert most of its electric energy into? a. light energy b. motion energy c. sound energy d. thermal energy

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

Asystematic approach to problem solving is called a (an)
