Why is it difficult for many sea creatures to live in the intertidal zone?
The intertial zone is where the ocean meets the shore
Would you know you're moving in a train if there was no friction and you could not see out of the train ie can't see objects going past?
If the train is moving at a constant velocity, and therefore in an intertial reference frame, then, no, you could not tell that you were moving.
If to travel back in time you had to reach faster than the speed of light how would you stop if in theory you cannot see anything in front or behind you?
I think that if you cut your energy, you would eventually slow down, also, you could induce drag. Relative to its own intertial frame of reference, it is not possible for any object to actually accelerate to the speed of light, let alone surpass it. If you could reach light speed, there would be no passage of time for you.
What is the principle of accelerometer in intertial navigation system?
The principle of accelerometer is that change the acceleration into voltage signal. At the beginning, the acceleration a is changed to displacement by mechanical structures such as differential capacitive, then displacement x is represented by changing in capacitor dC. A readout circuit is required to detect this capacitor changing. Hence, the changing capacitor is transfered to voltage bu using a charge amplifier. However, noises alwalys exist. Therefore, a Low pass filter is needed to filt the high frequency noise.
Explain the principle involve in the collision of car?
Newton's Law.First law: When viewed in an intertial reference frane, an object either is at rest or moves at a constant velocity , unless acted upon by an external froce .Second law: The acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass.Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body.

What is twin paradox?
It isn't truly a paradox. Here's the problem: A spaceship leaves earth for a trip at high relativistic velocity. Aboard is one twin, the other having remained on earth. The ship is moving away from earth at high speed, and returns to earth at high speed, therefore it's time is dilated, so the twin on the ship ages more slowly and should return to earth having aged less than his earthbound counterpart. However, from the perspective of the ship, it is the earth that is moving away at high velocity, and the earthbound twin should be the one aging more slowly. The paradox dissolves when the nature of each frame of reference is taken into account. The earth is an inertial frame of reference. The spaceship, since it must undergo several positive and negative accelerations to make the round trip, is a non-inertial frame. Only the viewpoint from the intertial frame is valid. The explanation is far too long and involved to go into here, but you will find one of the best and most detailed explanations in Paul Davies' book "About Time" on pages 62 to 65.
Einstein twin paradox theory?
It isn't a theory, and it isn't truly a paradox, except to those who don't understand the relationship. Here's the problem: A spaceship leaves earth for a trip at high relativistic velocity. Aboard is one twin, the other having remained on earth. The ship is moving away from earth at high speed, and returns to earth at high speed, therefore it's time is dilated, so the twin on the ship ages more slowly and should return to earth having aged less than his earthbound counterpart.

What is an intertial frame of reference?
Assuming you mean "inertial" frame of reference... it is any point of observation from which other objects appear to be still or in motion relative to you. For example... On an airplane flying at 35,000 feet. All the other passengers appear to you to be sitting in their seats or walking down the aisle at a leisurely pace... If you tossed a ball in the air, it would appear to go straight up and fall back into your hand... To someone on the ground, you and all your fellow passengers seem to be hurtling thru the sky at 500 mph. And the path the ball follows is not straight up or down. You and your fellow passengers share the same inertial frame of reference. In a similar sense, the earth under your feet appears to be still and all the objects seem to move or not move in relation to the still earth. In fact the earth is spinning... beyond that it is revolving around the sun, beyond that the entire solar system is moving in a galaxy that is, itself spinning, and the entire galaxy is also moving thru a universe that is expanding... Each of these are other inertial frames of reference. Einstein's theory of relativity states that none of these frames of reference is preferred... and that all observations, including those relating to time, dimension and speed, are entirely relative to one's inertial frame of reference. Thus different observers in different frames of reference perceive things differently. because even time varies with frame of reference, this renders such concepts as simultaneity specious. If time itself passes at different rates for different observers, then no two events can actually be said to happen at the same time.
Man made object that travels faster than light?
Currently, there really isn't anything that can move faster than the speed of light, man-made nor natural, possibly not even alien. In theory, warp drives would work, but would require enormous amounts of fuel, which we currently do not have. Also, in order to move faster than the speed of light, you would have to accelerate some constantly to move at the speed of light. The faster something travels, the harder it is to move it faster. Consider this: If you are pushing a stroller with, lets say, a Rubik's Cube inside it, then continue to push it faster and it will be increasingly harder and harder to accelerate the item. Soon you'll be pushing a car, then a skyscraper, soon the mass of the moon and then the mass of the sun and whatnot. Which means the faster an object moves, the more mass it has and the more force it will require to accelerate it. Now, at the speed of light, the object would be at infinite mass, therefore infinite force, to continue to push it, which does not exist in a finite universe.
