moments
moment nickname is Nm
Nm is want to measure the turning effect.
force marries distance from pivot and gave birth to moment of force.
force x distance from pivot = moment of force (Nm)
ciri" Nm :
- state magnitude (Nm)
-directions (CW o CCW )
clock wise = counter clockwise
equilibrium is a friend of inertia.
since inertia is one lazy fella (refer to first note)
equilibrium then oick up the same habbit.
so equilibrium is when resultant force = 0 (zero)
"i need to apologize to mark sim in the first place "
SORRY SIM, this way i learn much better.
let marksim be object and
let pitak be centre of gravity.
stability is when marksim wont fall if roy push him
if mark sim is short and fat ( whish is totally impossible)
the stability will increase.
marksim wont tople down if the pitak is somewhere above / in the base area (his feet lor)
equilibrium got 3 race. I AM NOT BEING RACIST PEOPLE!! *totallyrandom*
those are :
stable race :their pitaks will rise and fall back.
unstable race : their pitaks fall further away.
neutral race : their pitaks remain the same level of its support.
NOTHING PERSONAL SIM. SORRY :D cant think of any other name~ hehe
work energy and power
energy's nickname is joules
let cinema be energy
cinema got two movies, Ep and Ek.
the upcoming movies are elastic (man), gravitaional (???), and chemical .
energy is super strong so it cant be destroyed, and it is always there, since energy got no parents. no body is able to create energy .
tall object prefer to watch gravitational than kinetic but short objects are the other way around.
Ep = m. g . h ( marksim gigit hassan )
Ek = 1/2 mv^2 ( 1/2 marksim itu vina^2)
force marries distance and gave birth to work.
w = fd
if you want to lift roy, the first thing you need to do is find his mass that will tell you how much force is needed to lift him up. this only occur if both of u dont move.
force want to push object up on inclined plane. so need to find force ( mass x height/lenght)
and proceed to work = force marries distance.
power nickname is watt or joule /seconds
PRESSURE
nickname is Pa
if area loss weight, pressure will gain weight.
(jhonny)depth and (dennisity)density affect pressure in liquid.
p = hassan di gampar ( height.density.gravity)
P1V1=P2V2
hydraulic machine loves to stop a car and control the speed of it.
equation of Pressure is .01 x 10^5 Pa
well then, im drained and i just forced my brain out for those stupid ideas . need to stop talking nonsense. good night guys. cudnt take it anymooo =.=
all credits goes to : same with the other post #part 1
