Potential and Kinetic Energy.
The law of conservation of energy. Energy cannot be created. Energy cannot be destroyed. It can only be converted from one form to another.
The unit of energy is joules.
The formula for potential energy is mgh, M is equal to Mass, g is equal to gravitational acceleration and h is equal to height.
When we fall, potential energy starts getting converted to kinetic energy. Just before we land, all potential energy gets conveerted to kinetic energy.
To calculate kinetic energy, kinetic energy is equal to 1 upon 2 into m into v square, where m is equal to mass and v is equal to velocity.
