In the picture above, a person is using 40J of energy to rub their hands together on a cold day. The friction between the hands is helping to create the conversion of what two types of energy?

Question

Potential Energy is transformed into Thermal Energy
Potential Energy is transformed into Electromagnetic Radiation
Kinetic Energy is transformed into Thermal Energy
Kinetic Energy is transformed into Magnetic Energy

Answer 1

When a person rubs their hands together, they are using kinetic energy from the motion of their hands. The friction generated between the hands converts this kinetic energy into thermal energy (heat), which helps to warm up the hands on a cold day. Therefore, the correct conversion is:

Kinetic Energy is transformed into Thermal Energy.
