The Three Laws of Motion From Sir Isaac Newton Tell us why and how things move Or why and how they refuse First regards Inertia Next Acceleration And lastly is the Law Of Action and Ree-action These Classical Mechanics Work from apples to planets And study of these forces We term as “Dynamics” [Break] Think of Inertia As a kind of stubbornness Explaining change resistance That is what the First Law does [Break] Moving stuff continues Resting stuff stays still Till some outside force Unbalances that will [Break] Here on Planet Earth From air, liquid, ground Friction forces slow things down While others act to move things ‘round [Break] But absent are such forces In the depths of empty space Moving stuff keeps speed and course And resting stuff holds its place [Break] Now the Second Law Of Acceleration Gives the relationships In form of an equation [Break] Know that Force equals Mass Times Acceleration And if that seems complex Hear this explanation: [Break] To move something faster We must apply more force And when the thing is heavier Same speed needs more force, of course [Break] Lastly, the Third Law of Action and Ree-action Whose very name gives us clues That forces always come in twos [Break] Means if you push a thing It will push right back It’s the force we feel When giving balls a whack [Break] Force direction opposite But magnitude the same And with a simple slogan Its truth we can proclaim [Break] For every action there is ann Equal opposite ree-action But equal there is none To Sir Isaac Newton [Break] The Three Laws of Motion From Sir Isaac Newton Tell us why and how things move Or why and how they refuse First regards Inertia Next Acceleration And lastly is the Law Of Action and Ree-action These Classical Mechanics Work from apples to planets And study of these forces We term as “Dynamics”
