In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag). This is the steady gain in speed caused exclusively by the force of gravitational attraction. All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the bodies; the measurement and analysis of these rates is known as gravimetry. WebGravitational field strength (g) is measured in newtons per kilogram (N/kg). The Earth's gravitational field strength is 9.8 N/kg. This means that for each kg of mass, an object will experience 9. ...

WebNov 16, 2024 · Double the distance and it's 1/4 as strong. Triple the distance and it's 1/9 as strong. Ten times the distance gives a field 1/100 as strong. Sun's gravity in the neighborhood of earth is 6 millimeters /sec^2. Out in the Main Asteroid Belt it is less than 1 millimeter/sec^2. WebThe 9.8 m/s^2 is the acceleration of an object due to gravity at sea level on earth. You get this value from the Law of Universal Gravitation. Force = m*a = G (M*m)/r^2. Here you use the radius of the earth for r, the distance to sea level from the center of the earth, and M is the mass of the earth.
