    kinetic energy is: the energy of a moving object. the formula for this is 1/2*mass*velocity^2 in symbols 1/2*m*v^2

    Formul description: the work needed to accelerate a body from rest to its current velocity

    Light enegry: I've never heard of light energy before now if ur talking about the brightestness of the bulb than that is called luminosity a buy product of lighting sources is also heat energy, transfer of light is also done by photons you could say these carry the light energy.

    Potential energy: is energy which depends on mutual positions of bodies. The energy is defined as a work against a specific force such as gravity, an elastic force of a spring in a clockwork motor, electric force, etc (and is usually named after that specific force).

    chemical energy: Is a form of potential energy due to the breaking and forming of chemical bonds.

    Gravitational potential energy: the potential energy per unit mass of an object due to its position in a gravitational field.

    Hope this helps

    They are all different forms of Energy. Kinetic energy is the energy of a moving object. Light energy is the energy carried by tiny packets called PHOTONS. Potential energy is a property of any object that has stored energy (like a stretched rubber bacnd). Chemical energy is energy derived from rearranging chemical bonds. Gravitational Potential is the energy that is needed to remove an object of mass from a gravitational field and carry it to infinity. i can write more...but i need to know what level of study you are at. School??

    What Does Chemical Energy Mean

    Kinetic Energy: Energy that a body has as a result of its motion. Mathematically, it is defined as one-half the product of a body's mass and the square of its speed.

    Light Energy: Light is a type of energy (and the tiny part of the electromagnetic spectrum that we can see). The fastest that light can travel is 186,300 miles per second. Visible light has a wavelength from 10 -7 m to 10 -8 m. LIGHT SPECTRUM Light can be broken up into into its component colors (for example, by passing light through a prism) - this is a spectrum. Light from the Sun can be broken up into the colors of the rainbow (red, orange, yellow, green, blue, indigo, and violet).

    Potential Energy: The energy stored in a raised object (eg the weights in a grandfather clock). Potential energy equals mgh, where m is mass, g is the acceleration of gravity, and h is the vertical distance from a reference location. It is called potential energy because the energy can be regained when the object is lowered. This type of potential energy is sometimes called gravitational potential energy in order to distinguish it from elastic potential energy: see elastic energy.

    Chemical Energy: Potential energy stored in chemical bonds of molecules.

    Gravitational Potential Energy: A type of potential energy. Gravitational potential energy is associated in the interaction of an object with the earth. It is defined to be equal to the mass of the object times the gravitational acceleration times the distance of the object from the ground.

    Energy which is defined as the capacity to do work manifests in different forms.

    kinetic energy is energy possessed by a body by virtue of its motion;potential energy is the energy possessed by virtue of its position.together kinetic and potential energies are called as mechanical energy.

    potential energy is also called as stored energy as the energy stored in a spring.

    when a body is taken to a height by doing work on it against gravity the work done gets stored as gravitational potential energy

    we can use light to do work.you would have heard of the photo electric cells.photo means light.

    the crackers when burst give out light and sound because of the chemical energy stored in them.

    basically there is only on source of energy for this wonderful planet of ours namely the solar energy.every known form of energy originated from that.

    though there are different forms of energy,they are all interconvertible.this intercovertibility is known as the law of conservation of energy

    kinetic energy means the energy gained by virtue of motion of body.light energy is the energy emitted by light,potential energy is the energy stored in a body during rest,gravitational force is the force by which the earth pulls a body towards itself.

    KE: It is the energy acquired by the body by the virtue of its motion.

    PE: It is the energy acquired by the body by the virtue of its position.Ex:Water in a dam.

    LE: Light is energy and travels trough space.It not only makes things visible but also raises its temperature and exerts pressure on them.

    CE: It is also a form of energy .Ex:Battery.In a torch chemical energy converts into light and heat energy.

    GPE:The GPE of a two particle system is -GMm/r2(r square)where m,M are the masses of the particles and the PE is chosen to be zero when the separation is infinite.
