Gravitational Fields

Important

Gravitational fields are created by mass

Gravitational Field Strength

Equation

where:

  • is the gravitational field strength ()
  • is the gravitational constant
  • is the mass of the object ()
  • is the radius of the object ()

Gravitational Force

Equation

Remark

Recall that bending fields creates force. This is how gravitational force is created.

Gravitational Energy

Recall that a . We also know a joule is the same as a newton-meter. So we multiply force by radius to get .

Equation

Another way to interpret this is the area under the graph of vs .
