Which of the following is not an example of potential energy?
a.)The energy stored in a pile driver
b.)The energy stored in a stretched spring
c.)The energy of a body moving across a horizontal surface
d.)The energy in the water at the top of a waterfall
c. is not PE.
Its C because its moving
The correct answer is c.) The energy of a body moving across a horizontal surface. This is an example of kinetic energy, as the body is in motion. Potential energy refers to stored energy that has the potential to be converted into other forms of energy. The energy stored in a pile driver, the energy stored in a stretched spring, and the energy in the water at the top of a waterfall are all examples of potential energy.
To determine which of the options is not an example of potential energy, we need to understand what potential energy is. Potential energy is the energy possessed by an object due to its position or state.
a.) The energy stored in a pile driver: This is an example of potential energy. When a pile driver is raised, it has the potential to do work when it falls.
b.) The energy stored in a stretched spring: This is also an example of potential energy. When a spring is compressed or stretched, it stores potential energy that can be released to do work.
d.) The energy in the water at the top of a waterfall: This is another example of potential energy. Water at the top of a waterfall has gravitational potential energy due to its elevated position.
To determine if c.) The energy of a body moving across a horizontal surface is an example of potential energy, we need to consider that potential energy is associated with an object's position or state. In this case, the body is moving across a horizontal surface, which suggests kinetic energy (energy of motion) rather than potential energy. Therefore, c.) The energy of a body moving across a horizontal surface is not an example of potential energy.
Thus, the answer to the question is c.) The energy of a body moving across a horizontal surface.
