Yes, and the classic example that all mathematics students study is the motion of a projectile.
Typically a ball is thrown (or a cannonball fired) at an angle to the horizon and pupils study its trajectory. With some simplifying assumptions, the trajectory is a parabola. Ignoring air resistance (a simplifying assumption), the only acceleration is due to the downward acting force of gravity.
This is a line. (It goes on forever both ways. It has one dimension because there is only one direction of motion on the line: forwards and backwards (you can't turn). Two dimensions allows for left and right, and three dimensions allows for up and down.)
One dimension is a line. It has length, nothing else. Picture a number line. Two dimensions is a plane. It has length and width. Picture a graph.
It's true that a point has no dimensions. But a line has one dimension, not two. A plane has two dimensions, a solid has three, and that's about all that ordinary people can visualize.
The length is one dimension. You can measure it along one edge of the floor. The width is another dimension. You can measure it along another edge of the floor. The height is the third dimension. You can measure it in the corner where two walls meet.
Two.
three dimention
One dimension has only one axis of possibilities. Motion in one dimension is motion on straight line. Two dimensions is motion on a plane. Two axes meet at right angles and extend in both directions. A point can be located anywhere that can be described as two points in this plane.

relative acceleration between two bodies in motion is the vector substraction of the acceleration of that bodies.
Rest and constant velocity.
Rest and constant velocity.
simple harmonic motion (SHM) the two summits of motion are an example
Acceleration refers to the change in velocity, which is a vector quantity, therefore, it means that acceleration can mean the change in speed or the direction of motion or both.
The question is, if not a maelstrom, certainly a melange at least.Especially noteworthy is the part where "acceleration of a body changesat constant velocity".Acceleration is the rate of change of velocity. If velocity is constant, then there isno acceleration. If velocity changes at a constant rate, then acceleration is constant.Velocity would have to change at a rate that changes, in order to have a changingacceleration.Now, what is it you're looking for ? A "linear or circular motion equation" ? There areoodles of them, describing the relationship among the position, displacement, speed,velocity, and acceleration, in one, two, or three dimensions, in rectangular, polar, andspherical coordinates, for linear motion, and an entire separate set of equations forcircular motion.
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
