Answer:
c. gravitational potential energy
Explanation:
Gravitational potential energy is the form of energy possessed by an object which is located at a certain height above the ground. This energy is given by:
[tex]U=mgh[/tex]
where:
m is the mass of the object
g is the gravitational acceleration (g=9.8 m/s^2)
h is the height of the object with respect to the ground
We have to note that gravitational potential energy is always measured with respect to a reference altitude (generally, the ground), because the value of h depends on the point chosen as reference.
