definition for wave?
A disturbance that travel from one medium to another and without causing permanent change to its displacement
Fagbenro
In physics, a wave is a disturbance that transfers energy through matter or space, with little or no associated mass transport (Mass transfer). ... There are two main types ofwaves: mechanical and electromagnetic. Mechanicalwaves propagate through a physical matter, whose substance is being deformed

what is physic
zalmia
Study of matter and energy
Fagbenro
physics is the science of matter and energy and their interactions
Acquah
physics is the technology behind air and matter
Doc
Okay
William
hi sir
Bala
how easy to understanding physics sir
Bala
Easy to learn

31. Calculate the initial (from rest) acceleration of a proton in a 5.00×106 N/C electric field (such as created by a research Van de Graaff). Explicitly show how you follow the steps in the Problem-Solving Strategy for electrostatics.
what friction
question on friction
Wisdom
the rubbing of one object or surface against another.
author
momentum is the product of mass and it's velocity.
Algayawi
what are bioelements?
Edina
Friction is a force that exist between two objects in contact. e.g. friction between road and car tires.

With regards to a shielded cable, is there an induced current on the shield when the center conductor is carrying an AC Current? What is the formula?
what is phenomena
no idea
Awoke
its phenomenon, an observable fact.

what is force
Force is the cause and momentum is its effect.
Salman
A force is a pull or a push on an object, causing an object to move or a moving object to stop.
Eklu
Find the velocity that make one full oscillation in 10 seconds and also makes 1.7meters in the same time
yes
Rafael
OK
Oluwaseun
17m/s
Eklu
17m/s
Gabriel
0.17
Devansh
17m/s
Harrison
how did you solve it
Acquah
t=10s a=1.7m v=? u=0 but v=u+at but u=0 v=at 1.7×10=17 v=17m/s that's how I solved it.
Eklu
kk
Acquah
How is a=1.7m?
El
a is an acceleration
El
eklu..... I respect u....
Doc
its relating to time and oscillation made.
Eklu
You mean A as an amplitude?
El
ok
Emmanuel
what is voltmeter
A voltmeter is a device use in measuring electric potential in a volt.
Find out the equation of a simple harmonic progressive wave that have 0.2m with a frequency of 550hertz.If the wave moves along a positive x axis with the speed of 330m/s
is there a summary for this whole physics book
I don't think there is a summary for this physics
nope
Idy
I want a guide book on Ray optics
Sharma
Where to get?
Sharma
ok
Jude
hi
Tina
pleasant evening
Idy
evening dr
Betman
what the difference between laws and principles
principle are like rules... it can change BUT LAW IS LAW... confirmed theory
Fortune
principle is a guiding belief Law is authority or instruction
Faruk
Hello want to study physics but it seems so difficult
Yes
Aifuwa
I read it but when I try to solve questions it seems difficult
Aifuwa
Jerry where are you from
Joshua
can i study some problem on motion and projection motion
Weamie
hello pls am new here so i want someone to highlight me on this "application of expansion/contraction
Awoke
want 2 do is just dat u rest for some minute,then u go back to the simple one nd one u understand and then go back to d difficult one,u will now understand it better.
rebecca
yess
rebecca
what of mine
Awoke
yess
rebecca
ok
Awoke
iam new here
Mohamed
u are welcome
Awoke
hello am new. am I welcome
Miracle
yes you are😁
clifford
we can all learn and help each other
Osei
yeah you are right
Neyaz
so we can all share our ideas on a certain topic
Osei
sure
clifford
in beginning all subjects are difficult need to work hard
Mohammed
hi guyz
Lamin
How can I understand physics
Thankgod
Where will I start from
Thankgod
(fundamentals of physics) start there
clifford
OK thanks
Thankgod
Hello, im college now, engineering, 1 years, what book of physics i must use, to be understand easily?
Megryan
try physics for scientist and engineers/ cutnell and Johnson
clifford
Okey po!
Megryan
Is not difficult if u really want to learn
Gabriel
hello guys
Okotie
i love physics but it is difficult for me to solve
Okotie
I just saw d group on my physics app
Charles
xame here
Kpogho
pls guys i need help on my physics understanding and i know that if we share ideas together we can make this world a better place using more advance level of technology cos we are the new generation and we need to make technology more advance and introduced to under develop countries.
Sammy
i think we need to b focus when learning or studying physics,making research on topics or words that seems difficult , putting them into practice or analyzing the idea to our day to day activities and introducing it to other.
Sammy
i just think that is a way we can improve and highlighting our selves on physics so that those who want to learn will learn and those who want to know will know that there is still some generation scientists who can improve technology today.
Sammy
i don't think if what i sed make sense but i still think it those
Sammy
physics is a course that goes like this, if you don't put in the work it doesn't matter how much help you get, you will never truly understand
clifford
what is this group for please?
Charles
if u ask people or internet for understanding u will get d idea of how physics play it's game on every topic
Sammy
hellow guys am persuing science laboratory technology which physics book should I use so that I understand the concepts of physics well
Nasike
yh me too
Ozuruonye
essential physics or new school physics is good but u can also download MCQs physics handbooks
Sammy
just for beginners
Sammy
is true
Ali
hello guys
Okotie
please who can teach me physics
Okotie
Ok
Zazy
i can
Sammy
hi
divine
pls am new here and I really want someone to teach me physics
divine
explanations on harmonic motion
