What is The type of energy of an object because of location?
What type of energy does an object have because of its position relative to another object that is pulling on it?
Gravitational potential energy is a type of energy that an object possesses because of where it is placed in a gravitational field. The higher the object the more energy it has, so if you had an object that was on the ground and then you put it on a high shelf then it would have more energy when it is on the shelf.
Is the type of image formed by a convex lens depend on the location of the object relative to the optical axis?
Light contains energy. This can be converted into other types of energy (for example, an object in sunlight will get hotter, because it absorbs the light); also, it requires some other type of energy to produce light (a radiating object cools down; you require batteries to operate your flashlight, or electrical energy from the outlet to operate your light bulbs).
