what is the meaning of third derive of the position in physical?
99360
In kinematics, the 3rd time derivative of position x(t) (x'''(t)) gives the rate of change of acceleration with respect to time (da(t)/dt). It is also known as jerk. This quantity is relevant in the context of problems involving rockets that have a mass that changes with time.

Don't forget...also in earth science (weather)\n\nDeposition in science can also mean going directly from a gas to a solid (i.e. frost on the ground).\n\nDeposition is the opposite of sublimation which is going directly from a solid to a gas. (i.e. dry ice)\n\n:)

I hope I can explain this....when you are aligning with three datums, your first datum (datum A) will contact your object at three points.  The second (datum b) at two and the third (datum c) at one.  If you rearrange the order of constraint on your object, you might actually move it.  It is based on degrees of freedom.\n\nAny object has six degrees of freedom....movement in three directions and rotation in three directions.  the first datums stops rotation in two direction and the second will stop rotation in the third....and it takes all three datums to stop translation.  So you can see that if you attach to the wrong datum first, you may be forcing the object to rotate or translate in a direction you don't really want it to....

Fundamental quantities are those used to derive other quantities.\n\nExamples are the Meter, Gram, and Liter and second.  These derive most other quantities of measure.  Learning those derivations will save you life in physics.\n\nExample of a derived quantity is the Newton which is the quantity of force.  A newton is a kg m/second squared.  How do we get this?  The equation for force is F=ma which is Force is the mass times the acceleration.  Accelaration is also a derived quantity.  It is the velocity change over time.  Velocity is also a derived quantity. It is the change in distance over time.  Therefore \n\nF=m s/t/t  mass is a base (kilograms) distance is a base (meters) and time is a base (seconds).\n\nHave fun.

Newton didn't derive it mathematically at first. He hypothesized it. That said, it is possible to derive it from Kepler's laws *if* you assume Newtonian physics in the form of F=ma. It turns out that Kepler's third law (about areas) shows that the force is a central one (pointed in the direction of the sun). That planets move in ellipses then restricts the possibilities to the inverse square law or the harmonic oscillator law. The fact that the sun is at a focus gives the inverse square law.

The subscrips indicate that mulitples of the symbol they follow.  Like the AgNO3 the three means that there are 3 oxygens.  The two after the () means there are three whole molecule though, that can be placed infront as a coeffient.

First requires technical knowledge but reaction time is less important.  Third is more of a reaction position, so it depends on the player.\n\nI would vote for third overall, though.

You just want me to do your science homework, don't you?  Somehow I suspect the answers are in your textbook, if you just look hard enough.  Okay, here we go.\n\nInertia is the tendency of an object to resist a change in its motion.  With intertia expressed as p.  Momentum increases if the mass or velocity increases.  Not sure where the final two sentences are going, or if you're looking for verbs or what.  Good luck.

Let v1=C-B , v2=A-C , v3=B-A be the three displacement vectors making up the sides of the triangle. Define f1,f2,f3 to be the three forces X,Y,Z each rotated 90 degrees counterclockwise. Then f1 is parallel to v1, and so on. That is:\n\nf1 = s1*v1\nf2 = s2*v2\nf3 = s3*v3\n\nwhere s1,s2,s3 are three scalars. It's only necessary to show that s1=s2=s3 to prove that the three forces are proportional to the three opposite side lengths (|f1|/|v1|=|f2|/|v2|=|f3|/|v3|). This is easily done as follows:\n\nSince the forces are in equilibrium (f1 + f2 + f3 = 0):\n\ns1*v1 + s2*v2 + s3*v3 = 0\n\nMultiplying (v1+v2+v3)=0 by s1 and subtracting from the above equation:\n\n(s2-s1)*v2+(s3-s1)*v3 = 0\n\nSince v2 and v3 are linearly independent both coefficients must be zero\n\n-->\n\ns1 = s2 = s3\nQED.

isometric means 'same length'\nwhat this means is that a muscle has the same length, and thus no actual movement takes placeduring the exercise.\nfor example: for the triceps:  if you put your forearms against the wall so that your elbows are bent 90 degrees, and then push against the wall, the wall will resist your motion, but you will be activating the triceps muscle.
