potential to acoustic energy
The energy transformation in a wind up toy is potential energy --> Kinetic energy
There is no energy when there is no wind. Also, it is expensive to initially set up.
Kinetic energy
Wind Energys potential is that it generates electricity & and using wind to pump up water.
Potential energy.
RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.
A wind up radio is a great device if you need a radio and have no electricity or batteries. These come in handy if there is a storm and you lose power or in case of emergency.
The energy transformation in a wind up toy is potential energy --> Kinetic energy
It can vary, but wind-up radios can last up to an hour or two on one full wind-up.
There is no energy when there is no wind. Also, it is expensive to initially set up.
Setting up wind mills can be expensive but using the wind energy for everyday appliances can actually save you up to $2000 a year.
Kinetic energy
Solar powered radios will last far longer than wind-up radios, provided there is adequate sun.
The wind-up radio was invented by a British man - Trevor Baylis. It is wound up by an integral handle, which winds a mainspring (a larger version of the mainspring found in a watch. The spring slowly unwinds, turning an internal generator - which powers the radio. See related links to Wikipedia pages on the inventor - and the radio.
NopeNo, potential energy would be, for instance, a spring that is compressed. It could cause motion if released. It is stored energy. The light bulb uses electrical energy, which it converts to light and heat energy. potential energy is like when you wind up a torch or a radio

Wind up radios are ones which a user must use some type of hand crank in order to generate power to the radio. Amazon has a variety of wind up radios one can purchase with prices varying depending on model.
