Study Notes
Gravitational Field Intensity
- The formula for the gravitational field intensity (E) is: E = G * (M / r^2)
- Where G is the universal gravitational constant, M is the mass of the object, and r is the distance from the center of the object
Dependence of Gravitational Field Intensity
- The gravitational field intensity depends on the mass of the object and the distance from the center of the object
- It is directly proportional to the mass of the object and inversely proportional to the square of the distance from the center of the object
Variation of Gravitational Field Intensity with Distance
- The gravitational field intensity varies inversely with the square of the distance from the center of the object
- As the distance from the center of the object increases, the gravitational field intensity decreases rapidly
