Free Fall -- Resource

This video is about free fall; it includes a song and footage of falling to demonstrate the concept in real life. Free fall is when the only force acting on the falling object is the force of gravity, or 9.8m/s^2. No air resistance!

The pictures in the video are helpful to me. :)

Yeah I'm Freeeeeee, Free Faaaaallin'.

Okay, so this topic is a bit difficult. I've found it easy to imitate what a ball would do in my head. This resource video is just like what I imagine.

~ The ball goes up/down, and falls with a constant acceleration of approximately 10m/s^2. Don't forget to square the seconds in your answers for acceleration!
~ Each second, it's velocity gets bigger (down) or smaller (up) by 10m/s.
~ No air resistance, only the force of gravity!

(Using the formulas for vertical distance [d=1/2at^2] and [v=at]...and the formula for horizontal distance, [v=d/t], we can solve for any variable with enough information).

PROJECTILE MOTION IS THE SAME IDEA.
But....the object is now thrown up or horizontally instead of simply dropped. The initial velocity is not 0m/s anymore. Also, the time starts at 0s, not 1s.



I made up a (maxim, proverb, adage, etc.) today. It's like this: Each dime is 10 pennies. What would it look like to have a penny dropped from a cliff, with an initial velocity of 0m/s? Think of its motion in your head. Would it get faster? How long does it fall if the cliff is 80 meters high? Hmm....

CHEERS.
