Apr 7, 2004 · Where G is the gravitational constant, M is the mass of the object that is pulling you and r is your distance from its center. It just so happens that on Earth, g is 9.8m/s 2. On any other planet you would have to adjust the values of M and r …

Jan 9, 2025 · Fgrav = m*g where d represents the distance from the center of the object to the center of the earth. In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth.

Oct 9, 2023 · Calculate the unknown variable in the equation for force, where force equals mass multiplied by acceleration. Free online physics calculators.

May 29, 2023 · The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s. There are slight variations in this numerical value (to the second decimal place) that are dependent primarily upon on altitude.

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.

Mar 19, 2025 · Near Earth’s surface, the gravity acceleration is approximately 9.81 m/s2 (32.2 ft/s2), which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres (32.2 ft) per second every second.

As others have said: 9.8m/s² is a measurement of how fast gravity causes you to accelerate. If you're falling at 10m/s, one second later you're falling at 19.8m/s. That means you're getting faster at a rate of 9.8m/s every second, or 9.8 metres per second per second.

QuickMath will automatically answer the most common problems in algebra, equations and calculus faced by high-school and college students. The algebra section allows you to expand, factor or simplify virtually any expression you choose.

$$g = \frac{GM}{r^2} = \frac{3.99\times 10^{14}\ \mathrm{m^3/s^2}}{r^2}$$ where $M$ is the mass of the Earth and $r$ is the distance from the Earth's center to the point for which you are doing the calculation.

The acceleration due to gravity (no other forces acting other than gravity) on the surface of the Earth is 9.8 m/s$^2$ which means that all bodies accelerate downwards at the same rate irrespective of their mass - remember no air resistance etc.
