The ball follows a parabolic path when thrown. In a vacuum (with no air or other forces acting upon it) the gravitational pull of the earth causes the ball to accelerate toward the earth (9.8m/sec
The ball would follow a straight line.
The rock follows a parabolic path.
speed and spin
Centripetal Force
zero
its velocity will b zero....
Follow the invisible path it is in the shape of an S.
in vacuum the ball would continue at the velocity thrown forever. in an atmosphere the ball would gradually slow under resistance until stationary relative to the atmosphere.
It would go up
travel horizontally
The direction of their motion changes, due to Earth's gravitation.
its velocity will be zero and acceleration will be -9.81 due to gravity
