Question

PLEASE HELP ME PLS PLS 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

Answer 1

i think it’s E not due

Answer 2

Option e is true. The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

What is the law of conservation of energy?

According to the Law of conservation of energy. Although energy cannot be generated or destroyed, it may be transferred from one form to another.

The following statements are true;

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

b)At the conclusion of its fall, all of its energy must be transformed to kinetic energy.

c)During its fall, the sum of its kinetic and potential energy must match the initial quantity of potential energy.

d)Total energy = Kinetic Energy + Potential Energy.

Hence, option e is correct.
