Bookmark or Share- Acceleration due to gravity - Simple English Wikipedia, the free ...At the surface of the Earth, the acceleration due to gravity is roughly 9.8 m/s 2 (32 ft/s 2). The average distance to the centre of the Earth is 6,371 km (3,959 mi). Using the constant , we can work out gravitational acceleration at a certain altitude. Example: Find the acceleration due to gravity 1,000 km (620 mi) above Earth's surface.
- Standard gravity - WikipediaThe standard acceleration of gravity or standard acceleration of free fall, often called simply standard gravity and denoted by ɡ0 or ɡn, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is a constant defined by standard as 9.806 65 m/s 2 (about 32.174 05 ft/s 2).
- Metre per second - WikipediaAccording to the definition of metre, [1] 1 m/s is exactly of the speed of light. The SI unit symbols are m/s, m·s−1, m s−1, or m s . [2] 1 m/s is equivalent to: 1 foot per second = 0.3048 m/s (exactly) [7] 1 mile per hour = 0.447 04 m/s (exactly) [8] 1 km/h = 0.27 m/s (exactly) [9]
- Gravity - Math is Fun9.8 m/s2 is the acceleration due to gravity near the Earth's surface. Nearly everything in our lives happens near the Earth's surface, so that value gets used a lot, and is written as a little g: The average value is 9.80665 m/s2, but values are different around the world, such as Calcutta at 9.78548, London at 9.81599 and Tokyo at 9.79805.
- What does it mean to say that the gravity of the Earth is 9.8 m/s2?The acceleration of gravity (also referred to as the gravitational field strength) at the surface of the earth has an average of #9.807 m/s^2#, which means that an object dropped near earth's surface will accelerate downward at that rate.
