It might be more accurate to say that you need to understand potential energy. Whether you want it or not, potential energy exists in our Universe.
Potential energy can be useful as an energy storage, for example, in a water dam. When the water is allowed to fall down, it can move turbines, generating electricity.
kinetic or potential energy
You need potential energy for it to move foreward.
No, potential energy does not require the input of cellular energy. Potential energy is the energy stored within an object due to its position or condition, such as gravitational potential energy or elastic potential energy. This energy can be released or converted to other forms without the need for cellular energy.
Potential energy because you use it only when you need it
To calculate potential energy, you need to know the object's mass, acceleration due to gravity, and height above a reference point. For kinetic energy, you need the object's mass and velocity. Potential energy is energy stored in an object's position, while kinetic energy is energy due to motion.
nopes for our cars need kinetic energy
Potential energy is pretty much the potential for kinetic energy. The less kinetic energy there is, the more potential... On the other hand, if you need gravitational potential energy, then the higher the object is placed above the ground, the more GPE it has.
Potential energy because you use it only when you need it
Chemical energy is a form of potential energy stored in the bonds of chemicals. When these bonds are broken, the potential energy is converted into other forms of energy, such as kinetic energy.
Potential and kinetic energy are related in that potential energy is stored energy that can be converted into kinetic energy, which is the energy of motion. When an object has potential energy, it has the potential to move and therefore has the potential to have kinetic energy.
Potential energy is stored energy. It has nothing to do with consuming or using energy - although you need to use some other energy to increase an object's potential energy. For example, in the case of gravitational potential energy, an object above ground level (or any other reference level chosen) has a positive potential energy, while an object below ground level has a negative potential energy.
There is chemical potential energy, heat potential energy, elastic potential, and gravitational potential energy.
