for a object in free-fall what will the acceleration (cm/sec2) on the y axis versus time(sec) on the x axis graph look like?
When there is no frictional air resistance, the acceleration is constant: 9.8 meters per second per second. Air resistance causes a gradual reduction of the acceleration to zero. At that point, the "terminal velocity" is achieved.
what does a velocity - time graph look like for a free fall object?
