The strength of the gravitational field is also called the gravitational acceleration. The gravitational acceleration of a particle which is placed at some distance <math>r</math> from an object of mass <math>m</math> is equal to:

<math>g = {G m \over r^2}</math>

where <math>G = 6.67 \times 10^{-11}</math>. 

'''(a)''' Neptune: <math>g = {(6.67 \times 10^{-11})(1.03 \times 10^{26}) \over (2.43 \times 10^7)^2} = 11.6 m/s^2</math>
 
'''(b)''' Jupiter: <math>g = {(6.67 \times 10^{-11})(1.9 \times 10^{27}) \over (7.14 \times 10^7)^2} = 24.8 m/s^2</math>
 
'''(c)''' Neutron star: <math>g = {(6.67 \times 10^{-11})(10^{30}) \over (2 \times 10^4)^2} = 1.67 \times 10^{11} m/s^2</math>
