motion of a simple pendulum
For example, if you keep on stacking squares (two dimensional figure) on top of one another, it will slowly form a cuboid (three dimensional figures). There is a mathematical way of calling it. Google it!
It is a figure that is flat. For example: triangle, square, pentagon...ect. A three dimensional figure is like a sculpture. Example: pyramid, cube prism...etc.

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.

Circular motion is a type of two-dimensional motion that is not always projectile motion. In circular motion, such as a car driving around a curve or a satellite orbiting a planet, the object is constantly changing its direction without necessarily being launched upwards. This motion can involve acceleration due to the changes in velocity direction.
A motion along straight line is called rectilinear motion. In general, it need not be one - dimensional; it can take place in a two dimensional plane or in three dimensional space. But, it is always possible that rectilinear motion be treated as one dimensional motion, by suitably orienting axes of the coordinate system.

In two-dimensional motion that is not projectile motion, the object may have acceleration even if it is not accelerating overall. This is because the object's velocity can change direction in two dimensions without necessarily changing its magnitude, leading to acceleration along curved paths. Projectile motion, on the other hand, involves acceleration only in the vertical direction due to gravity while the horizontal velocity remains constant.

An example of three-dimensional motion is a car moving along a curvy road with changes in speed and direction. This motion involves motion along the x, y, and z axes as the car moves forward, turns left or right, and goes up or down hills.
