Question

An example of kinetic energy being converted into heat energy is
A.) the sun
B.) a generator
C.) a snickers bar
D.) rubbing your hands together

Answer 1

Explanation:

As you say, kinetic energy of large objects can be converted into this thermal energy. For example, if you drop a water balloon onto the ground, its kinetic energy is converted mostly to thermal energy. If the balloon weighs 1 kilogram and you drop it from about 2 meters, it will heat up by less than .

Answer 2

D) rubbing your hands together is an example of kinetic energy being converted into heat energy.

Explanation:

• Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases.

• Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat

• When hands are rubbed, there is kinetic energy in the atoms.

• This energy is converted into heat energy due to motion of atoms and that is why we feel warm.

• Sun involves nuclear energy.

• Generator involves mechanical energy converted into electrical energy.
