What machine converts gravitational energy into elastic energy?
A gravity-powered clock, such as a grandfather clock or a torsion pendulum clock, converts gravitational energy to elastic energy using a weight-driven mechanism. The weight slowly descends due to gravity, causing the clock's spring or pendulum to wind up and store potential energy as tension in the spring or material of the pendulum.
Why is a pendulum not a reliable time standard?
The pendulum is not a reliable time standard mostly because of friction and gravity. To be a reliable time standard, a pendulum would need to form a continuous arc that did not deviate over time. Gravity is always trying to get the pendulum to stop and friction causes the pendulum's fulcrum to resit continued movement. Eventually, a pendulum will stop moving and remain stationary unless acted upon by an external force.
What device that transforms gravitational energy to kinetic energy?
Anything that falls. Some examples are: -- A waterfall -- A ball rolling down a hill -- A sailplane, when it is NOT climbing in a thermal -- Any pendulum, when it is moving TOWARD the center of its swing -- Anything you drop. The gravitational potential that it has relative to the floor while you're holding it in your hand is exactly the kinetic energy it has when it hits the floor.
What powers the grandfather clock?
Weights are traditionally used to provide the power, but some more modern clocks use a spring. The mechanism is powered by either lifting the weights up or turning a key that winds the spring.
Which of the best demonstrates kinetic energy?
A moving car is a good example of kinetic energy. The car's motion is powered by its kinetic energy, which is generated from its speed and mass.
Rose's cuckoo clock is powered by a pendulum which she has to push gently to the right of left couple of days after it stops swinging. rose's clock is a perfect example of the fact that?
Rose's cuckoo clock demonstrates the principle of a pendulum's need to be reset periodically to maintain its motion. This is in line with the law of conservation of energy, which states that energy cannot be created or destroyed, but only transferred or transformed. The clock's reliance on the pendulum's swinging motion for power exemplifies the conversion of potential energy to kinetic energy, allowing the clock to function.
Why do all pendulums swing at the same speed?
Most pendulums are operated by a spring, when the spring looses its tention it can no longer keep the pendulum swinging. Others may work on a different system but the system in not perpetual and will loose its ability to keep the pendulum swinging. As a point of interest you canot use a pendulum in space.

What are wind powered vehicles and what do they need to work?
Well. A wind powered vehicle is a vehicle that is powered by the wind obviously. An example of a wind powered machine would be a sail boat, a kite perhaps, or a hang glider.

What is an example of technology powered by solar energy?
Solar Energy Applications1.Solar Lanterns, 2. Solar energy powered Signalling system
Which country does a solar powered car race take place every year?
There are many across the world in different countries. For example, there are several solar powered car races in the US.
How solar powered things work?
Solar powered things work when they reflect off the sun. For example, if you have solar power energy it reflects off the sun making energy and then you can use it.
How many times have wings for powered flight evolved in protostomes?
Wings for powered flight have evolved multiple times in protostomes, with the best-known example being in insects. Other protostomes that have evolved wings for powered flight include some groups of arthropods, such as butterflies and dragonflies.

The hard drive is an example of a nonvolatile storage device?
Yes It retains information even when powered down. vs RAM which is a volatile storage device because the information is lost when it's powered down.
