Question

select the statement(s) that accurately support the law of conservation of energy. eating a candy bar gives a person the electromagnetic energy they need to convert to mechanical energy to walk. the law of conservation of energy states that energy can be transformed from one form to another. the law of conservation of energy states that energy cannot be created or destroyed. a roller coaster demonstrates how kinetic energy and potential energy are transformed as the coaster car goes up and down hills. energy is not lost in this process. a toaster is an example of how electrical energy is transformed into thermal energy. energy is not lost, just transformed from one form to another.

Explanation:

• The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
• Eating a candy bar: Chemical energy (in the candy) is converted to mechanical energy (for walking), which is a form of energy transformation.
• Roller - coaster: Kinetic and potential energy transformation without energy loss (in an ideal case, considering no non - conservative forces like friction in the basic concept for this law demonstration).
• Toaster: Electrical to thermal energy transformation.

Answer:

All the statements (Eating a candy bar gives a person the electromagnetic energy they need to convert to mechanical energy to walk; The law of conservation of energy states that energy can be transformed from one form to another; The law of conservation of energy states that energy cannot be created or destroyed; A roller coaster demonstrates how kinetic energy and potential energy are transformed as the coaster car goes up and down hills. Energy is not lost in this process; A toaster is an example of how electrical energy is transformed into thermal energy. Energy is not lost, just transformed from one form to another) support the law of conservation of energy.
