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.Know More
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 in Motion & Mechanics
Expansion tanks function on the principle of thermal expansion, stating that water expands when heated. When the water tank is heated its volume will expand significantly and the overflow will spill into the expansion tank, which is attached to the water supply pipe and prevents the water pressure of the main water tank from getting too high.Full Answer >
The principle of rocket propulsion follows Newton's famous third law of motion, which states that to every action there is an equal and opposite reaction. A rocket engine travels by expelling mass in one direction while at the same time using the reaction to move in the other direction.Full Answer >
The Law of Octaves is about the patterns of elements in the Periodic Table, stating that when elements are aligned according to their atomic weight, every eighth element shares similar properties. For example, hydrogen, fluorine, chlorine, bromine and iodine are all on the same interval.Full Answer >
Motion is defined as the action of changing position or location. Motion, along with force and energy, are concepts relevant to mechanics, a subject of physics. Within mechanics, there is a more specific field of study called kinematics, and this is the most basic level of mechanics.Full Answer >
