重さ

Also known as gravitational weight

In science and engineering, the weight of an object is a quantity associated with the gravitational force exerted on the object by other objects in its environment, although there is some variation and debate as to the exact definition.

AI overview

Weight is the force that gravity exerts on an object, pulling it downward toward Earth or another large body like a planet or moon. It matters because understanding weight helps us measure how much force gravity applies to objects, which is essential for everything from building structures that won't collapse to designing spacecraft that can escape Earth's pull.

重さ（おもさ、weight）または、重量（じゅうりょう、weight）は、物体についての厳密な物理量ではなく、日常語として使われる文脈では、全く異なる次の２つの意味がある。 1. * 物体の質量(mass)の意味。計量単位はキログラム(kg) 2. * 物体に働く重力の大きさ、すなわち力(force)の意味。計量単位はニュートン(N) かつては工学分野においては、物体の質量とそれが及ぼす力（または荷重）を厳密には区別せずに議論や計算を行っていた（重力単位系）が、現在では厳密に区別している。
