Object can Possess Energy because of its Motion, Position and Deformation

Objects draw energy from a variety of sources, which include their motion (kinetic energy), position (potential energy), and deformation (elastic potential energy).
An object’s kinetic energy is directly related to its motion. An item in motion has kinetic energy. The amount of kinetic energy an object has depends on two factors: its mass and its speed. The formula for calculating kinetic energy is KE = 1/2 m v^2, where m represents mass and v represents velocity (speed in a particular direction).
Potential energy relates to an object’s position or state. Common examples include gravitational potential energy and elastic potential energy.
Gravitational potential energy is an object’s energy resulting from its position in a gravitational field, often due to its height above the ground. This is calculated using the formula GPE = mgh, where m is the mass of the object, g is the gravitational field strength (approximately 9.8 m/s^2 on Earth), and h is the height above the ground.
Elastic potential energy is stored in objects when they are compressed or stretched. For instance, a stretched rubber band or a compressed spring possesses elastic potential energy. The energy stored can be released, doing work on another object when the deformation is removed.
Behaviour of elastic objects can be modelled using the formula EPE = 1/2 k e^2, where EPE stands for elastic potential energy, k represents the spring constant, and e is the extension of the object.
Notably, these forms of energy can be transformed from one type to another. For example, an object sliding down a slope converts its potential energy into kinetic energy. Similarly, when a compressed or stretched object is released, its stored elastic potential energy is converted into kinetic energy.
Understanding these principles is crucial in calculating work done, as work is essentially the process of energy transfer. In physics, ‘work’ refers to the effort required to transfer energy from one object or form to another.
Finally, remember the law of conservation of energy asserts that energy cannot be created or destroyed, just transferred or transformed. This is vital in working with any problems or scenarios involving energy conservation.
