Question:
Calculate the force of earth's gravity on a 1-kg mass at the earth's surface. The mass of the earth is {eq}6.0 \times 10^{24} {/eq} kg and its radius is {eq}6.4 \times 10^6 {/eq} m. Does the result surprise you?
Gravitational Force:
Any and all two bodies in the universe exert a gravitational force of attraction onto each other. The gravitational force as modeled by Newtonian physics incorporates the masses of the two bodies and follows the inverse square law. For everyday objects, the gravitational force is absurdly small that it becomes negligible. Gravitational forces usually only have measurable values when at least one of the objects is massive (like the Earth).
