The conservation of mechanical energy


The law of conservation of energy is one of the basic laws of physics and therefore governs the microscopic motion of individual atoms in a chemical reaction. The law of conservation energy states.

In a closed system, i.e., a system that isolated from its surroundings, the total energy of the system is conserved.

The law of conservation of energy can be seen in these everyday examples of energy transference

  • When you push a book across the table, the energy from your moving arm is transferred from your body to the book, causing the book to move.
  • When kicking a football that is sitting on the ground, energy is transferred from the kicker’s body to the ball, setting it in motion.
  • The dog ran in into the Christmas tree and knocked it over. Energy was transferred from the moving dog to the stationary tree, causing the tree to move
  • When the car hit the curb it broke apart. Energy from the moving car was transferred to the non-moving cement, causing it to move
