Question

How does friction play a role in the total energy? What energy is created due to friction?

Question 4 options:

kinetic energy


potential energy


thermal energy


sound energy

Answer 1

Friction plays a significant role in the total energy of a system by converting kinetic energy into other forms of energy due to the contact forces between surfaces. When friction acts between two objects in motion, it dissipates kinetic energy primarily into thermal energy, which is heat. This occurs because the frictional force causes the surfaces to rub against each other, generating heat as a byproduct of this interaction.

Among the options provided, the energy created due to friction is:

**thermal energy.**

While some sound energy may be produced due to friction (like a squeaking noise), the primary form of energy produced as a result of friction is thermal energy.
