20. A very full shopping cart is harder to move than an empty shopping cart. Which law best describes this action?
*
Law #1
Law #2
Law #3
Law #1: Newton's First Law of Motion, also known as the law of inertia, states that an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. This law does not specifically explain the difficulty in moving a full shopping cart compared to an empty one.
Law #2: Newton's Second Law of Motion states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. This law does not directly explain the increased difficulty in moving a full shopping cart compared to an empty one.
Law #3: Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This law does not directly address the difficulty in moving a full shopping cart compared to an empty one.
Based on the given information, none of the laws specifically address the difficulty in moving a full shopping cart compared to an empty one.
