Question

the law of conservation of energy states that...
energy can be created or destroyed.
energy is made of matter.
energy cannot be created or destroyed, but it can change forms.
energy cant change forms.

Explanation:

The Law of Conservation of Energy is a fundamental principle in physics. It states that energy is a conserved quantity, meaning it cannot be created or destroyed. However, it can change from one form to another (e.g., potential energy to kinetic energy).

• The first option is incorrect because it contradicts the law (energy can't be created or destroyed).
• The second option is wrong as energy and matter are different concepts (though related by \(E = mc^{2}\), energy isn't "made of" matter in the sense of composition).
• The fourth option is incorrect since energy does change forms (e.g., in a pendulum, gravitational potential energy converts to kinetic energy and vice - versa).

Answer:

Energy cannot be created or destroyed, but it CAN change forms.
