The constant of proportionality in this law is known as the gravitational constant; it is usually represented by the symbol G and has the value 6.670 × 10−11 N-m2/kg2 in the meter-kilogram-second (mks) system of units. Very accurate early measurements of the value of G were made ...
The surface of constant gravity potential,W0, that closely approximates mean sea level is known as thegeoid. If the constant normal gravity potential,U0, on the normal ellipsoid is equal to the constant gravity potential of the geoid, then the gravity anomaly on the geoid is the difference be...

The acceleration due to Earth’s gravity has a (roughly) constant value anywhere on the surface and points directly to the center of mass of the planet: g = 9.81 m/s2. Given this constant value, the only things you need to calculate GPE are the mass of the object and the height of...
Homework Statement A 4.0 kg mass is pressed down on a vertical spring of spring constant 400 N/m, compressing it to 0.250 m. After it is released, the amount of kinetic energy this mass would have when it leaves the spring is ___. Homework Equations mgy(final) + 1/2 kx^2 (final)...
