Newton's First Law: "Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it."Newton's Second Law: Force = Mass x Acceleration or, Force = change of momentum x change of time.Newton's Third Law: For every action there is an equal and opposite reaction.How These Laws Apply To Our BallistaNewton's First Law: Our water balloon will travel at an unaltered rate if unaffected by gravity. Our balloon is affected by gravity so it will arc.Newton's Second Law: If we measure the mass of our water balloon, then calculate the force of the water balloon after leaving the ballista we then calculate the acceleration of our water balloon.Newton's Third Law: As the tension from the rope on the ballista increases the force of its release will be that much greater. |
