Question

There is a potential energy associated with gravitational

andspring forces. Is there also a potential energy associated
withfrictional forces?
A.) No, because gravitational and spring forces are the
onlyforces that have an associated potential energy.
B.) Yes, because gravitational, spring, and frictional
forcesare all conservative.
C.) No, because frictional forces are conservative,
whilegravitational and spring forces are not.
D.) Yes, because all forces have an associated
potentialenergy.
E.) No, because gravitational and spring forces
areconservative, while frictional forces are not.

Answer 1

Option E

Step-by-step explanation:

This can be explained as the only energy that can be associated with the conservative force is potential energy.

Conservative forces are those forces by which the work done depends only on the positions, i.e., initial and final and is independent of the path.

Also, potential energy is the energy due to the configuration, position and shape and is entirely dependent on these and can be recovered completely.

The potentially energy can be associated with each conservative force and can be transformed into kinetic energy or other potential energy forms.

While gravitational force and spring force are conservative in nature but friction force is non conservative force and thus potential energy can not be associated with the frictional force.
