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.
