HELPPP Plssss:

Imagine an object held at some height above the ground. It is released and falls toward the ground. Ignoring air resistance or friction, which of the following must be true?

a. Before it falls, all of its energy must be potential energy
b. At the end of its fall, all of its energy must be converted to kinetic energy
c. During its fall, the combination of its kinetic and potential energy must equal the amount of potential energy with which it started
d. Total energy = Kinetic Energy + Potential Energy
e. All of the above

According to the law of conservation of energy,Energy can neither be generated nor destroyed, but it may be transferred from one form to another.

The sum of all the energies in the system is the total energy. The location of in a system determines its potential energy value.

The following statement must be true;

a. All of its energy must be potential energy before it falls.

b. All of its energy must be converted to kinetic energy at the conclusion of its fall.

c. During its descent, the sum of its kinetic and potential energy must equal the amount of potential energy with which it began.

d. Total energy = Kinetic Energy + Potential Energy.

All of the above options are correct.

Hence, option e is correct.
