Is it true when a person standing on a moving escalator is relative to another person standing on the escalator?
Yes, the two people on the escalator are in motion relative to each other. However, their relative motion is different from being stationary on the same escalator, as they would perceive each other to be moving at a speed equal to the difference in their individual speeds on the escalator.
What is the statement of time dilation by Einstein?
In a broad sense it means that you see clocks carried by people moving relative to you move slowly. This effect is totally negligible in every day life by the way, the speeds need to approach that of light for the effects to be apparent. More specifically it states that time moves slower in inertial frames moving relative to yours.
What is a moving frame?
A frame of reference, in physics, is a particular choice of coordinate systems. Part of what Einstein's theory of relativity is about is that there's no such thing as a "preferred frame" ... one that is somehow "better" than any other. We're therefore free to choose our coordinate system in any way that makes the mathematics convenient for our calculations.A moving frame is one that's in motion relative to something else ... and since pretty much everything is moving relative to something else, we usually use the term when we're temporarily pretending that there's some "absolute" coordinate system, and we want to describe a frame of reference that's moving relative to that coordinate system. For example, we might use it to describe the frame of reference of people in a spaceship relative to a "static" frame of an observer on a planet.
What is movement in relation to a frame of reference called?
Relative motion is movement in relation to a frame of reference.
When you say a car is traveling at 80 km h it is understood to be moving 80 km h relative to?
Very important question ! One that's usually ignored.When we talk about the motion of anything that's 'tied' to the earth, like a car, an airplane, a boat,a rock, a person, etc. ... anything that's motionless on the ground until you push it ... we normally measureits speed relative to the ground, i.e. relative to a point on the surface of the earth.That's why the whole notion of an object's speed suddenly becomes very murky when we start talking aboutspacecraft and astronomical objects. In each of those cases, it's important to define the reference point,which is something that not too many people are accustomed to doing.
How do you loose blubber?
You loose it by not sitting on the sofa all day like some people. Go outside, and get moving.

A people moving conveyor-belt moves a 600-newton person a distance of 100 meters through the airport?
This question is not quite clear as to what answer is being sought out. This is more of a statement, so yes, a people moving conveyor-belt moves a 600-newton person a distance of 100 meters through an airport.
Are Jewish people considered short relative to the general population?

Why do people say he got his genes from a relative?
Because the relative is related to him/her
Which is the best reason for not using a moving car as a reference point?
Answer #1:A reference point should be stationary from the point of view of the observer.===============================Answer #2:As soon as you said a "moving car", you showed us that you already have areference point, and that the car is moving relative to it. If you want to usethe car as a reference point, fine and dandy. Then the car is not moving.The pavement on the road, the trees, and the people on the curb may ormay not be moving, but the car isn't. You can't say that the car is movingAND also say that it's your reference point.Everything in all of Creation is moving relative to other things. There's no suchthing as really moving or really stationary.
What is relative health?
