Lorraine pushed different objects to investigate the force needed to move objects with different masses. She followed a procedure during her investigation and recorded the results of her observations. William observed the change in motion for different objects as he was walking through his community. What is the difference between how Lorraine and William looked at force? The results from Lorraine's observations can be replicated.
