Gravitational potential energy to kinetic energy
When a ball rolls down a hill, potential energy is converted into kinetic energy. As the ball descends the hill, its potential energy decreases while its kinetic energy increases, due to the force of gravity. This conversion demonstrates the principle of conservation of energy.
A jack-in-the-box is a symbol of kinetic potential and mechanical energy because it stores potential energy when the spring is wound up. When the lid is opened, the stored energy is released, causing the clown to pop out due to the conversion of potential energy to kinetic energy. This demonstrates the transfer of mechanical energy in a fun and interactive way.
A waterfall demonstrates both potential and kinetic energy. The water at the top of the waterfall has potential energy due to its height above ground, which is converted to kinetic energy as it falls down.
How does the height of an object affect its potential energy? What factors influence the conversion of potential energy to kinetic energy in a system? How does the speed of an object impact its kinetic energy?

The conversion of potential energy to kinetic energy demonstrates the principle of energy transformation, which illustrates how energy can change forms while conserving total energy in a closed system. This process is fundamental in various physical systems, such as gravitational potential energy converting to kinetic energy during free fall. It highlights the interplay between different types of energy and the laws of physics governing their behavior.

It is an example of conversion of potential energy (at the top) into kinetic energy (at the bottom).

Potential and kinetic energy are related in that they are both forms of energy that an object can possess. Potential energy is the energy stored in an object due to its position or condition, while kinetic energy is the energy of motion. When potential energy is converted into kinetic energy, the object is in motion. This relationship between potential and kinetic energy demonstrates the transfer and transformation of energy within a system.
When potential energy changes to kinetic energy, it is called "energy transformation" or "energy conversion."
Not all potential energy changes to kinetic energy due to conservation of energy. Some potential energy may be lost as heat or sound during the process of conversion. Additionally, external factors such as friction can also play a role in preventing the full conversion of potential energy to kinetic energy.
At the top of the second hill, the coaster has maximum potential energy and minimum kinetic energy. As the coaster descends, potential energy decreases while kinetic energy increases due to the conversion of potential energy into kinetic energy.
Normally the heat and sound are forms of energy wasted in the conversion from potential to kinetic energy. By the conservation of energy principle the potential energy is converted to kinetic energy not withstanding energy losses.
