• A battery storing chemical energy.

• A wind turbine generating heat energy.

• A car engine burning fuel to produce light.

What is kinetic energy?

• The energy of an object at rest.

• The energy of an object in motion.

• The energy stored in an object due to its position.

• The energy released during a chemical reaction.

What is the role of reasoning in science?

• To connect evidence to claims and explain why the evidence supports the claim.

• To gather data without interpretation.

• To formulate hypotheses without testing them.

• To present findings without supporting evidence.

What does it mean to convert energy?

• To change energy from one type to another.

• To create energy from nothing.

• To store energy for later use.

What is a system in the context of energy?

• A collection of unrelated entities that do not interact with each other.

• A group of interacting or interrelated entities that form a unified whole, often analyzed to understand energy flow.

• An isolated entity that does not exchange energy with its surroundings.
