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 ( glydelle27@gmail.com )

4. In the absence of air resistance…
All bodies regardless of
SIZE
and
WEIGHT
It is found that
at the same location above the
earth’s surface fall
VERTICALLY with the SAME
ACCELERATION.

7. -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.

8. 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.

9. ACCEL RATION

10. 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,

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

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

15. x = y a = -g

16. 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
m = ?

17. t = 2.00 seconds
g = -9.8 m/s^2
= 0 m/s
y = ? (how tall?)

18. m

What time does the
ball reach its
maximum height?

19. m

What is the velocity of the
ball when it returns to its
original height?

20. m

What is the
maximum heigth of
the ball?

21. a. How tall?
b. What is the final velocity?
