===> A stone or a Baseball tossed straight up.
-- Leaves your hand with speed ---> kinetic energy
-- Slows down as it sails higher ---> loses kinetic energy
-- But gains potential energy as it moves higher.
-- The kinetic energy it's losing is changing into potential energy.
-- Eventually, it stops rising, when all of its kinetic energy is gone.
-- On the way down, its potential energy turns back into kinetic energy,
until it meets the ground with a healthy 'thunk'.
When a ball is thrown upwards, kinetic energy is gradually converted to potential energy as it ascends. At the highest point of its trajectory, the ball possesses mostly potential energy. As it descends, potential energy is transformed back into kinetic energy.
Answers #1 and #2:
A rock falling off a cliff.
(When the rock is on the cliff it represents a potential energy, but when it falls off, the kinetic energy is represented by the hole formed when the rock hit the soil, but it would be a good for nothing energy)
Another example is represented by a waterfall. The water that has yet not fallen down is the potential energy. When it falls and make a turbine linked to an alternator to rotate, the kinetic energy is transformed into electricity. So, we can say that this kinetic energy is valid as a form of energy. A rock falling off from a cliff is nothing but a potential energy....because when any kind of energy isn't able to perform a useful work, it would be a useless energy, a wasted one and doesn't count as a form of energy.

Answer #3:
The definition of Kinetic Energy is 1/2MV2. 'M' is the mass of the object,
and 'V' is its speed. Notice that the formula doesn't include any coefficient,
variable, or term of any kind that depends on whether or not the energy
accomplishes any useful purpose, or improves anyone's life. The mere fact
that a mass is moving is sufficient to establish the presence of Kinetic Energy.
As soon as the rock rolls off the edge of the cliff and begins to lose altitude,
it also begins to lose potential energy, and the steadily decreasing potential
energy is matched at every instant by its kinetic energy, as revealed by its
increasing speed as it falls. If it's moving, at any speed in any direction, then
it has kinetic energy.
When a pendulum is swinging, the energy is switched from kinetic to potential and back again twice in each cycle. Apart from the energy lost to friction that eventually stops the pendulum, the exchange of energy is a continuous process.
Throw a ball up (100% kinetic), and when it stops due to gravity, you have all that energy as (gravitational) potential.
One e.g. of potential energy changing into kenetic energy is a wind up car after it has been wound up.
Riding a bike down a hill. You gain potential energy on the way up, but on the way down you lose that potential energy and gain an equal amount of kinetic energy.
A ball being kicked with enough force to roll uphill is an example of kinetic energy turning into potential energy.

Which form of energy is converted to kinetic energy?
Potential energy is typically converted to kinetic energy. For example, when an object is lifted against gravity, it gains potential energy. When it is released and allowed to fall, this potential energy is then converted to kinetic energy as it moves downwards.
Why potential energy can not be converted into kinetic energy?
Potential energy can be converted into kinetic energy. For example, when an object is released from a height, its potential energy due to gravity is converted into kinetic energy as it falls. This conversion follows the law of conservation of energy, which states that energy cannot be created or destroyed, only converted from one form to another.
Can kinetic energy turn in to potential energy?
Yes, kinetic energy can be transformed into potential energy, and vice versa. For example, when a roller coaster reaches the top of a hill, its kinetic energy (motion) is converted into potential energy (height). Conversely, when the roller coaster descends the hill, the potential energy is converted back into kinetic energy.
Is Niagara falls a good example of kinetic energy being converted to potential energy?
Yes, Niagara Falls is a classic example of kinetic energy being converted into potential energy. As the water flows down the falls, it gains speed and kinetic energy, which is then converted into potential energy as the water rises higher above ground level.
Examples of the law of conservationof energy?
When a ball is thrown upwards, its initial kinetic energy is converted into potential energy at its highest point, showing the conservation of energy. In a swinging pendulum, the potential energy at the highest point is converted back into kinetic energy at the lowest point, following the law of conservation of energy. A roller coaster's gravitational potential energy at the top of a hill is converted into kinetic energy as it moves down the track, demonstrating the principle of conservation of energy.

What happens to potential energy that is not converted to kinetic energy?
If potential energy is not converted into kinetic energy (or into any other type of energy) then it remains potential. Potential energy does not expire.
Is potential energy was converted to kinetic energy?
It CAN be converted to kinetic energy, but it won't always do so.

What is the same has kinetic?
Potential energy can be converted into kinetic energy, as seen in a swinging pendulum where potential energy at the highest point is converted into kinetic energy at the lowest point.
Water draining from a tower is an example of what kind of energy conversion?
Gravitational potential energy being converted to kinetic energy
Is a radio an example of potential or kinetic energy?
A radio is an example of electrical potential energy because it relies on stored electrical energy to function. When the radio is turned on, this potential energy is converted into kinetic energy in the form of sound waves.
How does increasing speed affect potential energy?
Increasing the speed will increase the KINETIC energy, not the potential energy. Of course, the potential energy may eventually be converted into kinetic energy, for example if the object moves upwards.
How is potential and kinetic energy used?
Potential energy is stored energy that can be converted into kinetic energy when an object is in motion. For example, a roller coaster has potential energy at the top of a hill, which is converted into kinetic energy as it travels downhill. Kinetic energy is the energy of motion and can be used for various purposes such as transportation, electricity generation, or even in sports.
