This laboratory focuses on applying second law of Newton: F= m*a.  During this laboratory we made an experiment using “Lego robot”.  We put weight on one side of a rope and robot on another side of the rope.  Using different power we lifted the same weight, than we started changing weights but used the same power.  Therefore, we came to the conclusion: if we put more weight, acceleration goes down, using the same power; if we use more power with the same weight, acceleration goes up.  Therefore, we proved Newton’s second law.
