semiconductor
A semiconductor is a material that allows electricity to flow through it better than an insulator but not as well as a pure conductor. It is a vital component used in making computer chips and electronic devices.

使い方のコツ
Use this word when talking about the technology inside computers, phones, or the electronics industry. It is often used as a noun adjunct (e.g., 'semiconductor factory').
よくある間違い
Learners sometimes confuse it with 'conductor'. Remember that 'semi-' means 'half', so it is only half-way good at conducting electricity.

energy
A1Energy is the power that comes from things like electricity, coal, or the sun to make machines work or provide heat. It also describes the physical and mental strength that people have to be active and do things.
gravity
A1Gravity is the natural force that pulls objects toward each other, especially toward the center of the Earth. It is what makes things fall to the ground and keeps us from floating away into space.
friction
A1Friction is the force that happens when two surfaces rub against each other. It makes it harder for things to move and can create heat.
inertia
A1Inertia is the tendency of an object to stay still or keep moving in the same way unless a force changes it. In a general sense, it also refers to a lack of energy or a desire to stay unchanged.
frequency
A1Frequency is how often something happens in a certain amount of time. In science, it describes the number of times a wave or signal repeats every second.
atomic
A1Atomic relates to the very small parts called atoms that make up everything in the world. It is often used to describe science, energy, or very small things.
solvent
A1A substance, usually a liquid, that is used to dissolve another substance to create a mixture. In science, it is the part of a solution that is present in the largest amount.
reduction
A1A reduction is when something becomes smaller in size, amount, or importance. In science, it can also mean a chemical reaction where a substance gains electrons.
organic chemistry
A1Organic chemistry is the branch of science that studies chemicals containing carbon. It explains how living things are made and how materials like medicine and plastic are created.
inorganic
A1An inorganic substance is something that does not come from living things, such as plants or animals. In science, it refers to chemicals and minerals like salt, water, and metals that do not contain carbon-hydrogen bonds.
