Work is done when a force acts on a moving body. Work is done whenever a force moves something. Everyday examples of work include walking up stairs, lifting heavy objects, pulling a sledge and ...

Since energy is conserved (the gravitational force is conservative), we can use the work/energy equation to determine the speed of the satellite as a function of the distance R from O to P. Since the ...

ELLIE: So let's begin. JAMES: Energy is converted in a variety of ways, but the three most common ways are through heating, work done by forces, and work done when a current flows. ELLIE ...
