Stonebridge,
Thanks for your reply.
I looked up drag force and understand what you mean there.
Are you saying that since F=ma and the mass of a plastic golf ball is low so it is likely to deccelerate faster than the golf ball.
I believe what you are saying about drag force is that...
I discussed with my students that if force remains constant and mass decreases then acceleration increases (a=F/m). I also explained that if force remains constant and mass increases, acceleration decreases.
I know that there are a number of variables that play into this next situation and I...
