Answer #1

In the generation of electrical energy let us consider the water is at a height of h and it acquires the gravitational potential energy of 'mgh'

whenever it is going to fall down then the total gravitational potential energy is converted in to the kinetic energy and this is used to rotate the coil/loop present in the magnetic field.

the magnetic flux cut by the coil varies then induced emf is going to generated

e=-N (d/dt)

work done is equal to W=eq which is equal to the potential energy mgh.

You want to do an experiment to measure the conversion of gravitational potential energy to kinetic energy to heat by dropping 2.0 kg of copper off the roof of LEHS, a height of 14 m. How much will the temperature of the copper increase? (Hint: Remember that potential energy is measured in J but specific heat capacity problems usually use kJ.)

From this week's lab you learned that the change in gravitational potential energy of a falling body can be captured and stored as a rotational kinetic energy of a spinning disk. This gave you the idea of a regenerative driver for an elevator in a tall building. When an elevator goes down the corresponding change in the gravitational potential energy of the elevator is transformed into the rotational kinetic energy of a solid disk-shape flywheel which can be extracted and...

We can derive the potential energy stored in an ideal spring when it is stretched or compressed by computing the work done due to Hooke’s law. In this experiment we will be working with springs. When they are not being stretched by some external force, the coils of these springs are held tightly together by the spring’s rigidity. They are held so tightly that a small amount of weight can be hung from these springs, and they don’t stretch at...
