Wind turbines convert the kinetic energy of wind into electrical energy.
photosynthesis
Blowing wind has kinetic energy. This can be transformed into electrical energy using a turbine to transform the wind into rotational kinetic energy and a generator or alternator to convert the rotational kinetic energy to electrical energy. Water above a dam has potential energy from gravity and also from the weight of the water around it. Once it is moving or flowing down through the pipes it then has kinetic energy.
As the ball returns to its original shape, kinetic energy decreases and potential energy increases.
So the potential energy is the energy in the car at the top of the first slope. It changes into kinetic energy (Speed with mass) as it rolls down the hill. Then the electric motor winds it back up the hill, putting potential energy in the system again.
Sound is a mechanical ennergy besides potential and kinetic.
It converts to potential energy.
Yes. If you drop them, the potential energy will convert to kinetic energy.
By raising objects against gravity (upward)
Your body could could convert chemical energy into potential, kinetic, or mechanical energy.
If you fired a bullet vertically upward, it would have kinetic energy at first, when it gets to the top of its travel this would all have been converted to potential energy.
Yes, because potential energy is energy stored but kinetic is energy in motion.
The kinetic energy of the wind (moving mass of air) is (usually) converted into electric energy.
photosynthesis
True. It has "potential energy", in that gravity could be used to convert that "potential" energy into actual kinetic energy.
kinetic
Potential energy (turned into kinetic energy to drive the turbines), (turned into electrical energy by the turbines). Note the original source of this energy is the Sun (nuclear fusion).
Kinetic Energy is movement energy. The energy present in an object's movement. For example, if you run you convert chemical potential energy ( food eaten by you ) to the energy of running. It is often transfered from a potential energy.
