what is thrust
when an object is immersed in liquid, it experiences an upward force which is called as upthrust.
Phanindra
@Phanindra Thapa No, that is buoyancy that you're talking about...
Shii
thrust is simply a push
Shii
it is a force that is exerted by liquid.
Phanindra
what is the difference between upthrust and buoyancy?
misbah
The force exerted by a liquid is called buoyancy. not thrust. there are many different types of thrust and I think you should Google it instead of asking here.
Sharath
hey Kumar, don't discourage somebody like that. I think this conversation is all about discussion...remember that the more we discuss the more we know...
festus
thrust is an upward force acting on an object immersed in a liquid.
festus
uptrust and buoyancy are the same
akanbi
Shii
a Thrust is simply a push

how did astromers neasure the mass of earth and sun
wats the simplest and shortest formula to calc. for order of magnitude
papillas
Distinguish between steamline and turbulent flow with at least one example of each
what is newtons first law
It state that an object in rest will continue to remain in rest or an object in motion will continue to remain in motion except resultant(unbalanced force) force act on it
Gerald
Thanks Gerald Fokumla
Theodore
Gerald
it states that a body remains in its state of rest or uniform motion unless acted upon by resultant external force.
festus
it that a body continues to be in a state of rest or in straight line in a motion unless there is an external force acting on it
Usman
derive the relation above
formula for find angular velocity
w=v^2/r
Eric
Why satellites don't fall on earth? Reason?
because space doesn't have gravity
Evelyn
Exactly everyone what is gravity?
the force that attrats a body towards the center of earth,or towards any other physical body having mass
hina
That force which attracts or pulls two objects to each other. A body having mass has gravitational pull. If the object is bigger in mass then it's gravitational pull would be stronger.For Example earth have gravitational pull on other objects that is why we are pulled by earth.
Abdur
Gravity is the force that act on a on body to the center of the earth.
Aguenim
what are the application of 2nd law
It's applicable when determining the amount of force needed to make a body to move or to stop a moving body
festus
coplanar force system
how did you get 7.50times

what is a frame of reference
0.88
Mharsheeraz
0.88
Iize
The system of geometric axis in relation to which measurement of Size, Position, or , Motion can be made. It has two types; 1) Inertial Reference Frame 2) Non Inertial Reference Frame

what is science
What is Matter?
Lloyd
mu
matter is anything having some mass and occupies some volume
Debi
Evans
is anything that occuple space
Diamond
I'm new here...I wana askng u how can I prepare any typ of test of atomic energy
gull
What is inertia of bank curve
Sunny
I wanna ask the different between coloumbs law and gravitational law of force
Femi
how do you got 27.8 m/s? please explain
A garden roller is pulled with a force of 200N, acting at an angle of 50 degree with the ground level.find the force pulling the roller along the ground
the force pulling the roller along the ground is the horizontal component of the 200N force.That is 200 Cos50 which is equal to 128.6N.
Bamidele
assist me to state the third law of thermodynamics
Mike
how do you know that its COS?
Yusuf
state 2nd law of thermodynamics?
mu
Good morning please, I want to be part of the conversation but I don't know the ethics of this platform so I kindly need your assistance if you would not mind
robert
yeah almost welcome
