Thermal Energy

1.How is mechanical energy different from thermal energy?

• mechanical energy includes kinetic and potential energy, and thermal energy includes only kinetic energy

• mechanical energy includes kinetic energy only, and thermal energy includes kinetic and potential energy

• mechanical energy is a property of whole objects, and thermal energy is a property of the particles that make up an object

• mechanical energy applies only to objects that are moving, and thermal energy applies only to objects at rest mechanical energy applies only to objects that are moving, and thermal energy applies only to objects at rest

Which is the is the mechanical energy of the object.

• kinetic energy
