Alright, I'm going to impart some basic science knowledge on you. By impart, I mean shove it down your throat; and by basic I mean stuff that governs our entire universe. Seems simple enough, right? Trust me, when you get into the formulae of it all, it complicates your definition of complex. I'm going to make it simple so everyone can understand and give a simple explanation along the way.(Too simple?)
Let's get started.
Newton's Laws of Motion:-
They teach this in grade school , blah ! blah ! I know. It's my blog, I'm telling it to you anyway. Heehee!
1. A body is said to be stationary until and unless acted upon by an external force.
MEANING : It basically says that if there is a cup on the table, it won’t move unless your lazy ass picks it up and moves it. Other factors like gravity are also taken in consideration when you push the cup off the table ,but , we know you won’t do that. Unless , you’re filthy rich and own a Cupboard full of cups.
2. The mass of a moving body is directly proportional to the external force applied and inversely proportional to the acceleration of the body.
MEANING : This one is hard to explain, remember this formula F= m X a
F - external force
m - mass of the body
a - acceleration of the body
You can remember this by "Fun equals me alone"(Yes, I made that up) . I will not go into the units of calculation. Just think, that more the body weighs (mass is not the same as weight) more force needs to be applied to move it. It will be more difficult to push an elephant than to push a baby elephant. Seems right!
3. Every action has an equal and opposite reaction.
MEANING : Most of you will be aware of this one. Like people say, your actions will bring upon consequences. It's somewhat similar. For example, when you row a boat (I've got big muscles coz of rowing, I keed ,I don't row, got big muscles though) you feel a resistance on the oar. You rowing is the action part, the resistance of the water to the movement of the oar is the reaction part. The harder you row, the more difficult it’ll become.
Okay, my class is officially over. Go back your Coffee drinking, ciggy smoking lives or whatever you naughty guys do behind your computer.
Ciao! (This one is for goodbye)
