An object appears weightless if:
There is no normal reaction force acting on it.
An object is weightless if:

final velocity
acceleration
(physics) a rate of change of velocity
time
A measure of change between two events or moments.
trajectory
Path of a projectile
projectile
An object in the air that is only subject to the force of gravity and wind resistance after it leaves the ground.
free fall
a state in which an object is gravitationally drawn to the earth's surface and is unaffected by any forces besides weight

net force
Acceleration depends on the
weight
A force that comes from gravity pulling down on any object with mass
balanced forces
forces that are equal in size but opposite in direction
