Southbridge Loop #4 - Gravity Traditional Cache

Please don't park along the highway, it's just not all that safe to do.

This is cache number four that will surround the Southbridge development of Shakopee.  They will be placed along City of Shakopee walking / biking paths.  Caches will be hidden and released during the first half of 2015.

Gravity is a force by which all physical bodies attract each other.  Gravity is what is holding you to the ground, and what holds the moon in it's orbit near earth.  Due to it's mass, our planet has an enormous amount of gravity force, but even your body has a small force of gravity.

Earth's gravity force is about 32.2 feet/second squared.  If you throw a ball up in the air, it is constantly accelerating back toward earth at 32.2 feet/second squared.  Even on the way up, it's speed is slowing at that rate, then for a brief moment it's not heading up or down, and then the ball accelerates at 32.2 feet/second squared downward until it hits the ground. 

Newton's law of universal gravitation is this:

Where F is the force, m₁ and m₂ are the masses of the objects interacting, r is the distance between the centers of the masses and G is the gravitational constant (or 32.2 feet per second squared).

Using this equation, you could figure out how much force F your body exerts on, say, a 16 pound bowling ball.
