Sir Isaac Newton's third law of motion is the inspiration for Newton Running's Active Membrane Technology. Replacing the foam and inherent energy loss of traditional running shoes.

LAW OF CONSERVATION OF ENERGY

The law conservation of energy states that energy can be neither created nor destroyed. The total amount of energy in a closed system is always the same. Energy can be changed from one form to another, but all the different forms of energy in a system always add up to the same total amount of energy, no matter how many energy conversions occur.

LAW OF UNIVERSAL GRAVITATION

The law of universal gravitation states that all objects in the universe attract each other by a force called gravity. The strength of this gravitational force depends on the masses of the objects and the distance between them.

The first part of the law explains why a bowling ball is much harder to lift than a table-tennis ball. Because the bowling ball has a much larger mass than the table-tennis ball, the amount of gravitational force between the Earth and the bowling ball is greater than the amount of gravitational force between the Earth and the table-tennis ball.

The second part of the law explains why a satellite can remain in orbit around the Earth. The satellite is carefully placed at a distance great enough to prevent the Earth's gravitational force from immediately pulling it down but small enough to prevent it from completely escaping the Earth's gravity and wandering off into space.

NEWTON'S LAWS OF MOTION

Newton's first law of Motion states that an object at rest remains at rest and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force. The first part of the law explains why a football will remain on a tee until it is kicked off or until a gust of wind blows it off. The second part of the law explains why a bike's rider will continue moving forward after the bike tire runs into a crack in the side-walk and the bike comes to an abrupt stop until gravity and the sidewalk stop the rider.

Newton's second law of motion states that acceleration of an object depends on the mass of the object and the amount of force applied. The first part of the law explains why the acceleration of a 4 kg bowling ball will be greater than the acceleration of a 6 kg bowling ball if the same force is applied to both. The second part of the law explains why the acceleration of a bowling ball will be larger if a larger force is applied to it. The relationship of acceleration (a) to mass (m) and force (F) can be expressed mathematically by the following equation: Acceleration = force/mass or Force = mass x acceleration.

Newton's third law of motion states that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. This law explains that a runner is able to move forward because of the equal and opposite force the ground exerts on the runner's foot after each step.
