explain 2D 3D AND 4D?

Question

AND 1D TOO.

Answer 1

1D is a line in time [time]
-----You would see a dot if there was any space for you to exist in.
2D is essentially a plane (square) in space time [time x length]
-----you would see it as a line
3D is essentially a volume (cube) in space time[time x length x width]
-----you would see it as a plane (square)
4D is essentially a hyper-volume (tesseract) in space time [time x length x width x height]
-----you would see it as a volume (cube)

if you where not taking time into the equation
1D is a line - line
2D is a plane - square
3D is a volume - cube
4D is a hypervolume - Hypercube (Tesseract)

Answer 2

1d is a line (length)

2d is a plane (length x width- like drawings)

3d is space (length x width x height- like 3d objects, things are
realistic and aren't simply images on paper)

4d is 3d but with time (where everything in space is given movement, since time is constantly going and going. Think of it like a flip-book, the pages keep on going steadily but there's an overall image that moves and changes)


You can see that with each further level, dimensions become more complicated but build upon the more simple dimensions.

Answer 3

2D=2 dimensional , 3D=3 dimensional, and 4D= 4 dimensional,2D is the plane, the geometrical object that has only width and length but no breadth, thats why we cant grip shadows that are 2D and it has XY dimensions.3D is the material world which can length,width and breadth, thats why we can grip any physical thing.and it has XYZ dimensions.the 4D is the main universal fact and this fourth dimension is the result of the birth of the Quantum physics.
physicists say that "time" is the fourth dimension of the universe and the whole universe is flowing in the direction of the time.and time has only one "only forward" direction. thats why you can see a glass downing from a table,travelling towards the floor and breakage, but you will never see a brokien glass,collecting peices,refilling the water,travelling up towards the table, and ...... this is entropy and......oooh i go tooo much.. any way time is the fourth dimension and it is 4D

Answer 4

2D = 2 dimensions = plain view. Like on a paper you see two dimensions (you see length and width)

3D = 3 dimensions = how you see an object (length, width and depth)

4D = 4 dimensions = it contains the dimension of TIME

Answer 5

2D is short for 2 dimensional, which has both x and y-axis. Therefore 3D stands for 3 dimensions, which has x, y, and z axis.

For examples, a car should be travelling in 2D, since it only moves forward, backward, right and left (unless it can fly!!!), and an aeroplane is moving in 3D, because it can also move vertically (z-axis).

Answer 6

2d Is like a flat picture with no dimension... 3d Is something with shade and shadow.. Err, I forgot 4d...

Answer 7

2D is like a picture.it has no depth.
left right / up down.
x axis y axis
3D is real life.
left right / up down / FORWARD, and BACKWARD
x asis y axis and z axis.
The 4th d is time.
everything, from our perpsective, only moves forward through time.
