potential energy because it has the ability to do work
Explanation:
A rock resting high in a cliff is an example of potential energy because it has the ability to do work. This form of energy is called potential energy.
- Energy is defined as the ability to do work. To do work, force must applied using energy to move a body through a particular distance.
- A body at rest is not doing any work. This is the case with potential energy of the body on a high cliff.
- At the state of rest, it is not doing any work.
- The potential energy of this body expresses the ability of such body to do work.

Answer:
Option D. Weight varies with location, but mass does not.
Explanation:
To know which option is correct, it is important that we have a background knowledge of mass and weight.
A brief summary of the difference between mass and weight is given below:
1. Mass is the quantity of matter present in an object while weight is the gravitational pull on an object.
2. The SI unit of mass is kilogram Kg) while that of weight is Newton (N)
3. Mass is constant while weight varies by location.
4. Mass can measured using a chemical balance or beam balance while weight can be measured using a lever or spring balance.
With the above information, we can see that mass of an object is always but the weight varies by location.
