Gravitational Field
When a unit mass experience a force within a gravitational field then, the force is called gravitational field intensity. This note has brief explanation of gravitational field and its intensity.
Summary
When a unit mass experience a force within a gravitational field then, the force is called gravitational field intensity. This note has brief explanation of gravitational field and its intensity.
Things to Remember
- Gravitational field is the space around the planet up to where the effect of gravity can be felt.
- When a unit mass experience a force within a gravitational field then, the force is called gravitational field intensity.
- The place which is the border between the gravitational field and space is called neutral point.

Gravitational Field
TheGravitational field is the space around the planet up to where the effect of gravity can be felt.
Gravitational field Intensity (I)
It is the force experienced by a unit mass of an object, within the gravitational field. Its SI unit is N/kg
The gravitational field intensity is calculated by using following formula:
If the object is on the surface I =
If the object is at height H =
If the object is at certain distance d =
Neutral point
They are the points which border the space with the gravitational field.Neutral points are those points in the space at where the gravitational field intensity is zero.The artificial satellites which have launched from the earth generally revolve around the neutral points.
