One dimensional motion is motion along a straight line.

Here is a VRML world showing an object moving along with a constant positive acceleration:

In the above animation we notice that the object moves faster and faster as it goes from left to right. This speeding up is one type of acceleration. Notice that the object covers more distance in the later time intervals than in the early ones. This is because in the later time intervals it is traveling faster.
