Answer:
change
Step-by-step explanation:
Energy can be defined as the ability (capacity) to do work or cause change in a system.
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
Energy is the ability to do work or cause change.
Basically, the various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.
The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Furthermore, the mechanical energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body.
Mathematically, it is given by the formula;
Mechanical energy = G.P.E + K.E
