能量守恒定律的英文是"Law of Conservation of Energy"。
Example:
Q: What is the law of conservation of energy?
A: The law of conservation of energy states that energy cannot be created or destroyed, but it can only be transformed from one form to another.
Q: Can energy be converted into heat?
A: Yes, energy can be converted into heat. When a body undergoes a change in temperature, it releases or absorbs energy in the form of heat.
Q: If a battery is connected to a light bulb, does the battery give up its energy to the light bulb?
A: Yes, the battery supplies energy to the light bulb through chemical reactions within the battery. When the light bulb is turned on, it absorbs this energy and converts it into light, which is then emitted into the environment.
Q: If a car is driven at a constant speed on a flat road, does the car's engine convert fuel into kinetic energy?
A: Yes, the engine of the car converts fuel into kinetic energy, which is used to propel the car forward at a constant speed. This kinetic energy is transferred to the wheels and transmitted to the road, causing the car to move forward.
