A wad of paper is dropped from a second-story balcony and falls through still air to the ground.
As it speeds up, what happens to the air resistance it encounters?
answer/question/discussion: ->->->->->->->->->->->-> :
The air resistance is overcomed by the gravitional force.
What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force is the sum of all the forces acting on the paper so as it fall the net force of the paper would be as following.
Net force = force of gravity + (- air resistance)
What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The acceleration is converted to gravitional acceleration that is 9.8m/s^2
If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The height is independ to force and acceleration so nothing gonna happen.
