Potential energy that depends on height is called
a. kinetic energy.
b. gravitational potential energy.
c. elastic potential energy.
d. mechanical energy.

b. gravitational potential energy.

Explanation:

Let's explain each of the different types of energy given in the question:

a. kinetic energy --> this is the energy related to the motion of an object. It is given by

where m is the mass of the object and v its speed.

b. gravitational potential energy.  --> this is the energy that depends on the height of an object. It is given by

where m is the mass of the object, g the acceleration due to gravity and h the heigth of the object.

c. elastic potential energy.  --> this is the energy stored in an eleastic object, like a spring. It is given by

where k is the spring constant and x is the compression/stretching of the spring.

d. mechanical energy. --> this is the sum of the kinetic energy and the gravitational potential energy of an object:

From the definitions given above, we see that the energy that depends on the heigth is

b. gravitational potential energy.

just took the test its not "d"
