Question

How can a stationary metal sphere have kinetic energy, the energy of motion?

• The metal is made of atoms, which are vibrating in place.
• The metal's molecules are moving around.
• The metal is made of atoms, which store potential energy.
• The metal sphere can be rolled.

The metal sphere can have kinetic energy even though it may appear stationary due to its atoms vibrating in place. This vibration of atoms contributes to the internal energy of the metal, which can be considered as a form of kinetic energy at the microscopic level. Additionally, if the metal sphere is subjected to external forces or is capable of movement, such as being rolled, it can also possess kinetic energy due to its motion.
