Default motion without force

Is it possible to move a particle without applying a force on it? One
observation suggests that the answer is 'yes'. And that phenomenon is
the bending of light in intense gravitational field (like that of a
huge star,say sun).


F= force experienced by the photon(s) due to the gravitational field
a= Acceleration of the photon due to F
M=mass of photon
Ms=mass of sun
r=Distance b\w sun and photon(s)

F=M*a
F=0*a=0

But the Gravitational force(f)=(G*Ms*M)/(r^2)

Where f=F

therefore,

F=f=M*a=(G*Ms*M)/(r^2)


= a=(G*Ms)/(r^2)

This acceleration causes the change in the velocity(Not the change of
the speed of the photon(s), but the direction aspect of the velocity)
of the photon(s) and this acceleration is caused by?.........Zero
force?


Thanx,
rAgAv.

Default motion without force


Whether, in the mean time, it is already clear as known, that every body
perseveres in its state of resting, or uniformly moving in a right line,
unless however, it is compelled to any change along that state by forces
impressed upon it.

However, the change of a motion, a definitely remains a proportionnal to the
motive of the force impressed, and therefore, it would be made in the
direction of the right line in which, however, that force is impressed.

Therefore, along that case, would be always along every action opposed an
equal reaction, or along, a mutual actions of two bodies upon each other,
which would be always an equal matter, and a definitely directed to a define
opposed directions.

As far as I know they change the direction of there movement because
they are following the shhortest in between point A and point B. The
shortest path is not a straight line due to deformation in space-time
caused by the pressence of a massive object like a star.

By removing a force from it.

There is an answer, but only one.

All particles are moving in free-fall. That means that there is no force
acting on them. That sounds insane, but there is an answer, only one.

Of course - remember Newtons first law.

One

F= force experienced by the photon(s) due to the gravitational field

Wrong model - you need GR for this - not classical mechanics.

Bill


Where f=F

therefore,

F=f=M*a=(G*Ms*M)/(r^2)


= a=(G*Ms)/(r^2)

Well, if you really mean 'Is it possible to change the state of motion
without an imbalanced force being applied', the answer is ...maybe. One
good example is how virtual particles can perturb the state of motion of
real particles. Now, a virtual particle is a character that pops into
existence and then very quickly disappears once again into the ether. But
while it is here it acts just like a real particle whose energy is
permanent. What you have here is a good example of imaginary energy being
able to perform real work. The long and the short of it is that you will
observe a particle moving around with no detectable mechanism.

it could be funny (:-)
if it was not sad !!! (:-( )

sad to se how far physics stupidity and cheating can go !!
