Which are two types of mechanical energy electrical and kinetic nuclear and chemical radiant and thermal elastic and gravitational

elastic and gravitational

Explanation:

Mechanical energy is the sum of the kinetic energy and potential energy of an object:

where

is the kinetic energy of the object (with m being the object's mass and v is the object's speed),

while U is the potential energy. Potential energy refers to the position of the object, and it can be of two types:

- Gravitational potential energy: , where g is the gravitational acceleration and h is the height of the object above the ground

- Elastic potential energy: , where k is the spring constant and x is the compression/stretching of the spring.

Therefore, the correct choice is:

elastic and gravitational

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
