Motion in two dimensions involves an object moving in both the x and y directions simultaneously. This type of motion is characterized by both a horizontal component (x-direction) and a vertical component (y-direction). An example is a projectile moving through the air, where the path is influenced by both horizontal and vertical forces.
Gravity
Two-dimensional motion that is not always projectile motion would be circular motion, where an object moves in a circular path. Two-dimensional motion that is not projectile motion and does not accelerate the object could be uniform circular motion, where the speed is constant but the direction changes.

Brownian motion
The period of a simple harmonic motion is the time it takes for one complete cycle of the motion to occur. It is the duration between two consecutive identical points in the motion, such as two peaks or two troughs.
Length and Width (or Height)
You can't have cubic feet in an area. Area is for two dimentions and volume is for 3 dimentions.20ft by 20ft is 400ft2
The dimensions (not dimentions) may be called length, breadth (or width) and height (or depth).

Height = 12.1cm
dimentions
it has one dimention.
