According to Newton's second law, the law of acceleration, if you push on a lego house and a real house with the same amount of force:

• The real house will be pushed further because it has more mass.
• The lego house will be pushed further because it has less mass.
• The lego house will be pushed further because it has more mass.
• Both houses will be pushed the same distance because mass does not effect motion.
