I thought that the acceleration of gravity was 9.8 m/s/s. Why does an object dropped from something high up, like from a plane, will reach a point where it won't accelerate anymore (terminal velocity)?
because objects slow down as they fall.
because the weight force is greater than the drag force.
because the drag forces are more than the weight force.
because the drag forces will balance out the weight.
