Why there is no contraction along the perpendicular direction?
Length doesn’t contract in the direction perpendicular to the velocity, since there is no motion relative to the rest frame. I think you misunderstood something. Length contraction in a moving body,does not occur in the perpendicular direction of its velocity (not length as you mentioned).
Why does Lorentz contraction happen?
Length contraction is the physical phenomenon of a decrease in length detected by an observer of objects that travel at any non-zero velocity relative to that observer. Length contraction arises due to the fact that the speed of light in a vacuum is constant in any frame of reference.
What is meant by Lorentz FitzGerald contraction?
Lorentz-FitzGerald contraction, also called space contraction, in relativity physics, the shortening of an object along the direction of its motion relative to an observer. Dimensions in other directions are not contracted.
Is Lorentz contraction real?
In several recent pedagogical papers, it has been clearly emphasized that Lorentz contraction is a real, physical deformation of a uniformly moving object, a phenomenon that exists regardless of the process of relativistic measurement by the observer [5,6,7].
Why do perpendicular forces not affect each other?
This perpendicular force from the tug does not affect the forwards motion of the ship because it is not pulling it forwards or backwards , the component in the forwards/backwards direction is zero. This means it has the samse effect in that direction as no force at all.
Can a vector have its component along perpendicular direction?
All vectors can be thought of as having perpendicular components. In fact, any motion that is at an angle to the horizontal or the vertical can be thought of as having two perpendicular motions occurring simultaneously.
What is Lorentz transformation give an equation of Lorentz transformation?
t = t ′ + v x ′ / c 2 1 − v 2 / c 2 x = x ′ + v t ′ 1 − v 2 / c 2 y = y ′ z = z ′ . This set of equations, relating the position and time in the two inertial frames, is known as the Lorentz transformation.
What is Gamma in Lorentz transformation?
Lorentz boost (x direction) where v is the relative velocity between frames in the x-direction, c is the speed of light, and. (lowercase gamma) is the Lorentz factor. Here, v is the parameter of the transformation, for a given boost it is a constant number, but can take a continuous range of values.
Is Lorentz contraction an illusion?
Yes, they most certainly are. They are both a result of what we measure—and what we measure is as real as things get. So, you heard them happening at different times, but you observed that they happened at the same time. …
In what direction does gravity always cause objects to accelerate?
Gravity causes objects to accelerate downward, whereas air resistance acts in the direction opposite to the motion and reduces acceleration. Terminal velocity is the constant velocity of a falling object when the force of air resistance equals the force of gravity.
Why does the speed of light not depend on length contraction?
If an observer says that you’re moving in only the x direction, then lengths only need to contract along that direction for you to preserve the speed of light. Since you have no motion in the y or z direction, no length contraction is needed in the perpendicular directions.
Can length contraction happen perpendicular to the direction of motion?
There’s also a very simple thought experiment that can be used to show that length contraction can’t happen in directions perpendicular to the direction of motion. Suppose a train is moving alongside a vertical wall that has a blue horizontal line painted on it.
Why does my body contract when someone moves past me?
Physicist: This probably should have come before the last post. Length contraction is a symptom of “tilted now planes”. For someone moving past you events physically in front of them happen earlier than they should (according to you), and events physically behind them happen later (according to you).
What is length length contraction?
Length contraction is a symptom of “tilted now planes”. For someone moving past you events physically in front of them happen earlier than they should (according to you), and events physically behind them happen later (according to you). Here’s the idea in a nutshell: you’re in the middle of a train when the front and back are hit by lightning.
