The law of interaction is also Newton's third law of motion, stating that each action brings an equal and opposite reaction. Forces are either pushes or pulls resulting from the interactions between objects. Some interactions come from contact, while others come from forces that act over distance, such as magnetism, electricity or gravity.Continue Reading
Many examples of the law of interaction take place in nature. Consider a person swimming in a pool. When the person's arms move through the water, they cause water to move backwards. However, pushing on the water only speeds the water up, not the person. There also has to be a force from the water pushing the person ahead to propel him across the pool.
Similarly, when a bus moves down a road, the wheels turn, causing the tires to grasp the road and push it to the back. Because forces are the result of interaction, the road also has to push the wheels ahead to some degree.
Some simpler examples include a golf club hitting a ball. Even though the club is doing all of the movement, when the club hits the ball, the ball also hits the club. When you push a chair to slide it across the floor, it also delivers a push back to your hand. Every force involves resistance as a part of this symmetrical relationship.Learn more about Motion & Mechanics
A primary example that demonstrates Newton's third law of motion is a flying airplane, where two pairs of action-reaction forces influence its flight. Other examples include a jumping child, bouncing ball and a falling fruit.Full Answer >
There are many factors concerning Newton's three laws of motion and seat belt use when a vehicle comes to a stop suddenly due to an accident. The first deals with inertia. According to HowStuffWorks, Newton put it this way: "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 on it."Full Answer >
Isaac Newton, a prominent mathematician and physicist, is famous for discovering several laws and theories of physics and motion that are collectively known as Newton's Laws. The laws that he is most famous for are the first, second and third laws of motion and the universal law of gravity.Full Answer >
The equations postulated by Newton according to his three laws of motion are applicable in projectile motion. These are: "S = Vit + 1/2at2," "Vf = Vi + at" and "2aS = Vf2 - Vi2," where "S" is the distance covered, "Vf" is the final velocity, "Vi" is the initial velocity, "t" is time, and "a" is acceleration. In this motion, acceleration (a) can be replaced by gravity (g).Full Answer >
