Answer: False
Explanation: Cuz its False, and its false, this message was approved by False.
When a ball is dropped from building, it will experience two forces: gravitational force( acting in downward direction) and air resistance(acting in upward direction i.e opposite to the motion of ball). This air resistance can be neglected because coefficient of viscosity of air is very less. So only gravitational force is responsible for downward motion of the ball.
