Kyle is swinging at the playground. As he moves from the top of the swing to the bottom he will . a. lose potential energy and gain kinetic energy
b. gain potential energy and lose kinetic energy
c. change kinetic energy into mechanical energy
d. change potential energy into mechanical energy

b. gain potential energy and lose kinetic energy

Explanation:

I could be wrong but heres a definition of each word. Potential energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. Kinetic energy is energy which a body possesses by virtue of being in motion.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
