NEWTON'S 3 LAWS OF MOTION
NEWTON'S FIRST LAW OF MOTION -- Every object that is in a state of uniform motion, tends to remain in that state of motion unless an external force is applied to it. In other words, there is a natural tendency for objects to keep doing what they're doing. All objects (including humans) resist changes in their state of motion. Unless there is an unbalanced force that comes in and knocks something loose and shakes it up, then the object will remain in the same state of motion.
Example of Newton's First Law of Motion -- Dirty dishes in the sink won't clean themselves. Certainly, you can use the dishwasher and make it easy on yourself but YOU STILL HAVE TO PUT THEM IN THE DISHWASHER! If you want something to change (move), an external force (you) has to be applied to it. In other words, you have to take action.
NEWTONS' SECOND LAW OF MOTION -- Heavier objects require more force to move the same distance as lighter objects. So we have force, mass, acceleration (F=ma). Force is equal to mass (times) acceleration. Acceleration is produced when a force acts on a mass. The greater the mass of the object that needs to be accelerated, the greater the amount of force needed to accelerate the object.
Example of Newton's Second Law of Motion -- Hmmmmmm . . . would it be easier to push a bicycle or a car if you had a flat tire? How much force do you think I would have to apply to create a five page website as opposed to this 5,000 page website? Yeah, it takes a lot of force on my part to accelerate and move this mass of a website at the pace I like to go.
NEWTON'S THIRD LAW OF MOTION -- For every action there is an equal and opposite reaction. In other words, for every force there is a reaction force that is equal in size, but opposite in direction. So whenever an object pushes another object it gets pushed back in the opposite direction equally hard.
Example of Newton's Third Law of Motion -- Let's just say that YOU are a rocket ship and you want to go to the Moon with your career. How much thrust do you think it will take to get you there? Your action (being the rocket) is to push down on the ground with the force of your powerful engines, fire, thrust and power, and the reaction is that the ground pushes you (the rocket) upward with the equal force of your rocket boosters. The more force from you, the higher you go baby!
