perpendicular
A perpendicular is a line that meets or crosses another line at a 90-degree angle. It is used in science and math to describe two lines that are perfectly square to each other.

자주 혼동되는 단어
Parallel lines never touch, while perpendicular lines cross at exactly 90 degrees.
Vertical means straight up and down relative to the earth; perpendicular can be at any orientation as long as it is 90 degrees to another line.
사용 참고사항
While 'perpendicular' is often used as an adjective, as a noun it refers specifically to a line that is at a right angle to another. It is very common in geometry and construction contexts.
자주 하는 실수
Learners often use 'perpendicular' when they simply mean 'vertical' or 'straight'. Remember it always describes a relationship between two lines.

hypothesize
B2To suggest a possible explanation for something based on limited evidence, used as a starting point for further investigation.
velocity
A1Velocity describes how fast an object moves in a specific direction. It is a technical word for speed used often in science and math.
momentum
A1Momentum is the power that a moving object has to keep moving. It depends on how heavy the object is and how fast it is going. It is also used to describe a plan or project that is growing and becoming more successful.
magnetism
A1Magnetism is a physical force that pulls certain metals toward each other or pushes them away. It is also used to describe a special charm that attracts people to a person.
radiation
A1Radiation is energy that travels through space as waves or very small particles. It comes from natural sources like the sun and from machines like X-rays in hospitals.
wavelength
A1Wavelength is the distance between two peaks of a light or sound wave. It is also used to describe when people have the same ideas and understand each other.
optics
A1Optics is the branch of science that studies light and how it interacts with things like lenses and mirrors. In modern usage, it also refers to how an event or action is seen by the public.
thermodynamics
A1Thermodynamics is the study of heat and how it moves. It explains how energy changes from one form to another, such as how heat can turn into movement.
atom
A1An atom is the smallest possible part of a chemical element. Everything in the world is made of millions of these very tiny particles.
reaction
A1A reaction is a response to an action or a situation. In science, it is what happens when two or more substances are mixed together to create a change.
