free falling bodies
DESCRIPTION
Hello! This is my PowerPoint Presentation on free falling bodies. Some transition might failed when viewing. so if you want a better presentation using this, you could ask me. The Galileo vs Aristotle part is kind-of a video presentation. You could find a better video on Youtube. For further question, just comment on the comment box below. or Send me an Email ( [email protected] )TRANSCRIPT

All bodies regardless of

It is found that
at the same location above the earth’s surface fallVERTICALLY with the SAME ACCELERATION.

FREEFALL

-is the motion of a body acted upon by gravitational pull only.
-motion that is free from other forces except the gravitational force due to the earth.

Imagine a straight number line that coincides with the motion.
Choose an origin.
Assign one direction as the positive axis.
The position of a falling object is specified by the y-coordinate of its location.

EACCEL RATION
How does gravity affect acceleration?
gravity /is/ acceleration!
You've probably heard of the "force of gravity," and you may have heard of the equation “F=ma.”
The thing about gravity is that it has its own number…
In a sense,

Use the formula from kinematic equation…
Change x = y
a = -g

It takes 2.00 seconds for a pebble released from the top of a building to reach the ground. How tall is the building?
12seconds
