potential energy
That is basically correct. While the meteor is in the air, its kinetic energy will be converted to heat, light, and sound energy. I believe you forgot the light energy. Once the meteor crashes into the Earth, yes, the kinetic energy will be transferred to whatever it crashes into. Much of this might then be converted to heat energy, but in the case of a large meteor, it might generate powerful tsunamis and earthquakes, which also carry away energy from the point of impact.
Kinetic energy is converted into force through the process of an object in motion colliding with another object or surface. When the object in motion comes into contact with another object, the kinetic energy is transferred, causing a force to be exerted on the object it collides with. This force is a result of the change in momentum of the objects involved in the collision.
Kinetic energy is the energy in a mass of matter that is in motion, the energy of motion. Potential energy (where mass is in a gravity field) can be converted into kinetic energy Chemical energy (of an explosion) can be converted into kinetic energy Electrical energy can be converted into kinetic energy (eg in an electric motor)
It CAN be converted to kinetic energy, but it won't always do so.
When potential energy is converted into kinetic energy, it is transformed into the energy of motion.
Potential energy can be converted to kinetic energy when it is used to do work.
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.
Kinetic energy is the energy of motion, while potential energy is stored energy that can be converted into kinetic energy. The two are related because potential energy can be converted into kinetic energy and vice versa.
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.
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.
Assuming it just rolls down a slope, without the engines working: gravitational potential energy will be converted to kinetic energy. The kinetic energy will eventually be converted to heat energy.
Chemical energy is being converted to thermal energy which is then converted to mechanical energy and finally to kinetic energy which moves the car. Kinetic energy is then converted to thermal energy in the brakes to stop the car.
