1.	Answer properly if you don't no the no need to tell I don't know in place of answer
Answer» Energy can neither be created nor destroyed, it can only be transformed from ONE form to another. The TOTAL energy before and after TRANSFORMATION remains the same. A body of mass'm is raised to height b. At A its potential energy is maximum and kinetic energy is 0 as it is STATIONARY. When body is allowed to free fall and it reaches at B, h is decreasing hence potential energy decreases and V is increasing hence kinetic energy is increasing. When the body is about to reach the ground level, h = 0, v will be maximum hence kinetic energy > potential energy ∴ Decrease in potential energy = Increase in kinetic energy This shows the continual transformation of gravitational potential energy into kinetic energy. Potential energy + Kinetic energy = Constant (MECHANICAL energy)

Answer»

Energy can neither be created nor destroyed, it can only be transformed from ONE form to another. The TOTAL energy before and after TRANSFORMATION remains the same.

A body of mass'm is raised to height b. At A its potential energy is maximum and kinetic energy is 0 as it is STATIONARY.

When body is allowed to free fall and it reaches at B, h is decreasing hence potential energy decreases and V is increasing hence kinetic energy is increasing.

When the body is about to reach the ground level, h = 0, v will be maximum hence kinetic energy > potential energy

∴ Decrease in potential energy = Increase in kinetic energy

This shows the continual transformation of gravitational potential energy into kinetic energy. Potential energy + Kinetic energy = Constant (MECHANICAL energy)
