Question

Select the correct answer. In which item is energy stored in the form of gravitational potential energy? A. a slice of bread B. a compressed spring C. an apple on a tree D. a stretched bow string

Answer 1

Answer:

C. an apple on a tree

Explanation:

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

b. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

$G.P.E = mgh$

Where;

G.P.E represents gravitational potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

In an apple on a tree, energy is stored in the form of gravitational potential energy.
