The ball will be traveling at the same speed when it returns to Earth.
Without air resistance, the path of a projectile over a small part of the Earth's surface, under the influence of gravity alone, is always a piece of a parabola ... as long as it's not launched straight up or straight down.
-- "free fall" -- absence of terminal velocity
absence of friction...no air resistance
-- "free fall" -- absence of terminal velocity
In the absence of air resistance (friction) objects will fall at the same speed. Hope this still helps :)
The path of a body not acted on by a force is a path without acceleration, a straight line. A straight line can be a flat line zero velocity or a slant line constant velocity. It cannot be a curved line, acceleration, changing velocity.
In the absence of air resistance, it doesn't.
A rabbit and a tiger fall at the same rate in the absence of air because there is no air resistance affecting their falling bodies.
A rocket plane does not have to fight against air resistance if there is no air.
Mountains, rivers, seas, and walking in the absence of motor vehicles. Sea travel was best.
The resistance of an imposing object to change it's movement. Intrinsic to mass,it is present in the absence of gravity.
Inertia - or the absence of any force making it change direction.
