All of us are familiar with the word energy. When we lack energy, we say we are tired and unable to do anything productive. So, what is energy and what are its various forms?
An energy that is stored in an object and not moving, but which has the potential to move is called Potential Energy.
The word Kinetic has its origin in the Greek language. In the Greek language, the word kinesis means "to move". This name was originally coined by William Thomson.
|Kinetic Energy (KE)||Potential Energy (PE)|
|KE is the energy possessed by an object by virtue of it being in motion.||PE is the energy possessed by an object by virtue of its position.|
|It can be transferred from one object to another and this happens during collisions.||Potential Energy, on the other hand, cannot be transferred from one object to another.|
|When Kinetic Energy is measured, the measurement is done at the point where the object is at the time of measurement. Ex: If a ball is traveling at a speed of 50m/s upwards and if we want to measure the Kinetic energy at a height of 3 meters above the ground, the measurement is done at that point and not with reference to another point.||When Potential energy is measured, the measurement is done by measuring the position from the reference position. If a ball is at a height of 10m above the ground and at rest, the potential energy is measured from the ground as a reference|
|The formula to measure Kinetic energy involves velocity and is measured as mentioned earlier.||Potential Energy is based on mass, gravity, and height.|
|Environment impacts Kinetic Energy and is relative to the environment||Potential Energy, on the other hand, is not influenced by environment.|
|Kinetic Energy is already moving and is not at rest.||Potential Energy is purely based on the position of the object and also the condition of the object.|
