Answer:
500 J
Explanation:
Emechanical=U+K,i.e., the mechanical energy Emechanical is the sum of the potential energy U and kinetic energy K.
So, the object has a mechanical energy of 200+300=500 J.
Answer:
Law of conservation of energy is one of the basic laws of the Physics.
Explanation:
According to the Law of conservation of energy, the total energy of an isolated system doesn't change, Energy may be transformed from one to another but the total energy of an isolated system remains constant. There have different forms of energy like- kinetic energy, potential energy, chemical energy, thermal energy , electrical energy. the potential energy is converting into kinetic energy in the water falls. When kicking a football, energy is transferred from the body of the kicker to the ball.
