Newton's Laws
Newton's First Law
"An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon" by an external force. This law is used in our Rube Goldberg machine when we launch our car on a flat surface at the beginning. This law is also demonstrated when we launch a different car (Lightning McQueen) at a support piece in a seperate step in our project.
Newton's Second Law
F=M*A. Force equals mass times acceleration. This means an object's acceleration produced by a net force is proportional to the net force's magnitude, in the same direction of that force, and is "inversely proportional" to the object's mass. This law is present in our project when both toy cars accelerate toward their target. The model Porsche 918 Spyder is a mass that is accelerating, therefore it has force and this law applies to it. The same goes for Lightning McQueen.
Newton's Third Law
"For every action, there is an equal and opposite reaction." This means that if a domino has the force of 1N and it hits another domino then the recoil force and hitting force is 1N. This law is used in our project nearly every time one object hits another object. From a domino hitting another, to a car hitting a domino, and to a ball falling onto a scale, our project demonstrates several examples of the third law.
In the image above, an airplane is flying. This image is demonstrating that no matter how fast the plane is going, there will still be thrust and drag, which are opposite forces.
