Which of the following is an example of potential energy? Check all that apply.
A. A child running across a field
B. A glass of water sitting on a table
C. A vase on the top shelf
D. A rock teetering at the edge of a cliff

Respuesta :

b and c
because they aren't moving,
so when and if they do move
they will gain kinetic energy,
but for now they have potential
energy. hope I could help :))

The answer is B,C,D.

In all the three cases potential energy is stored due to the object's position.

Consider the formula for Potential energy

Potential energy = mgh

Where m is the mass of the object

g is the acceleration due to gravity

h is the height at which the object is placed.

In all the three cases, the objects have a mass due to the gravity acting on it and all the three objects are placed at a height h from the ground. Thus from the above formula we conclude that potential energy is present in case of the vase,the glass of water on the table and the rock at the edge of the cliff.
