WebDec 17, 2024 · Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light. WebSince force is measured in newtons (N) and area in meters squared (m 2), one pascal is equal to one newton (N) of force exerted over one square meter (m 2) of area: 1 pascal (Pa) = 1N/m 2. Turning Forces. Force can make an object such as a lever turn around a fixed pivot point, or fulcrum. A turning force around a pivot is called a “moment.”

Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm.
