Drop Towers (Free Fall Rides)
Free Fall & Weightlessness
Acceleration to the ground in which riders experience
weightlessness
In free fall, no force pushing rider up
All bodies fall at the same rate
Greater the distance, faster the fall
Feel weight going up (pushed into seat)
Contact forces removed, in state of free fall
Only force of gravity (non-contact force)
In free fall, rider experiences weightlessness
No external objects exerting push or pull
Cannot feel force of gravity without opposing force
Momentarily air borne and lifted out of seats
Falling at same rate - g
Equations
For velocity of a falling body from rest;
v = gt
where t represents the time in which the body falls
g represents gravity
and v represents the velocity
Distance the body falls;
d = 1/2 gt^2
where d represent the distance ;
g represents gravity;
and t represents the time

Weightless Water
With plastic or paper cup p
oke two holes (approximately one-quarter inch in diameter) on opposite sides of the cup .
Fill the cup with water and cover
the holes with your fingers, and drop the cup from an elevated position.
What happens?
The water shouldn't spill out when in free fall, but will when the cup hits the ground/surface.
Why does this happen?
