If we ignore the effects of air resistance all objects
would follow a trajectory of exactly the same shape - this shape is called a
PARABOLA.
The ball will stay vertically below the plane if the plane flies at a steady
speed in a horizontal; line. The faster the plane is going when it releases the ball the further out
the ball will travel each second and so the greater the range. Knowledge of projectile paths is very
important when dropping supplies in famine relief areas.
