SEED Question 23.1
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 increases as the speed of an object increases.
#$&*
• What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force will accelerate the object changing its speed, its direction, or both its speed and direction.
#$&*
• What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The acceleration will increase.
@& Velocity will increase.
Acceleration will not increase. The force exerted by gravity is constant, which in the absence of other forces would result in constant acceleration.
However the air resistance, which is increasing, acts in the direction opposite the gravitational force, reducing the acceleration as the object speeds up.*@
#$&*
• If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> :
The net force will still accelerate the object just the same.
