Newton’s third law of motion states that for every action there is an equal and opposite reaction. How does this law differ from a theory?

• Laws can be changed with the addition of new evidence but theories cannot.
• A law explains a pattern in nature in more detail than a theory. 
• Theories are based on more evidence than laws.
