Falling

Falling is when the significant force \n acting upon an object is **gravity** and it is moving **closer** to the object it is experiencing gravity with (also known as “^^downward^^”)

\

Freefall

Regardless of whether it is moving further from or closer to the object it is experiencing gravity with, if gravity is the **only** significant force acting on an object, we say the object is in _______

Massive

The reason the Earth doesn’t really move is because… \n It is _______ and therefore has so much more inertia (resistance to change)

Accelerate

Gravity never stops pulling! (as long as things are close enough) \n This means that without an opposing normal (or other force) \n there is a net “unbalanced force” \n When there is an unbalanced force, objects _______________!

1. Slowing down
2. Speeding Up

In freefall, if an object is going up it is ________________. \n If it is going down it is _______________.

Increase

Proximity (how close things are to each other) \n Over HUGE distances, YES, the strength of gravity will ________ as objects get closer. Things accelerate, and the rate of acceleration changes. \n **But this is at** ***astronomical*** **levels.** 

1. Accelerates
2. Acceleration

* If you fall off of El Capitan in Yosemite and descend to its bottom, you **will not have fallen far enough** for the force of gravity to change. \n At smaller scales (such as at the surface of the Earth) simply the fact that gravity KEEPS pulling (providing an “unbalanced force”) ____________ objects in freefall. \n But the rate of ____________ is nearly constant.

The force of gravity is the..

* Product of the masses
* Divided by the square of the radius (or distance) between their centers of gravity
* Multiplied by the universe’s gravitational constant: \n 0.0000000000667 Nm2/kg2
