Which possible component of initial energy is caused by molecular motion within a material? thermal energy

Thermal energy

Explanation:

The internal energy of a system is widely known as thermal energy. Now, thermal energy is also called heat energy and it is an internal energy of a component which is produced when an increase in temperature causes atoms and molecules within the component to move faster and start colliding with one other.

Therefore, the more heat the is applied to the component, the hotter the substance and the more its particles move which in turn leads to a higher thermal energy.

The gravitational pull and the mass of a planet put it in it's place in orbit. It is the force that allows a planet/star to hold objects in orbit. Venus and Earth don't have the same mass or gravitational pull, because they would conflict in orbit. :)
