jesslily said:Sasha is probably 20 lbs lighter than Michelle. I think Sasha is smart enough to know the consequence when she thought about to block. If the accident happens, Sasha herself will be hurt the most. Larger people or objects produce more force. I don't think Sasha wanted to hurt herself and could not compete her full potential.
IIRC from jr high physics force is not entirely dependent on mass alone.
