Yes providing that the line is wide enough and that the can is equally balanced.
A sphere and a cylinder can roll straight.
Yes. If it is not straight, then it is not a line.
it just a straight line
If it is not straight, then it is not a line.
The word straight does have an antonym, which is crooked. So perhaps a crooked line is the opposite of a straight line.

A straight line has no vertex.
If it is not straight, then it is not a line.
Displacement of a straight line is zero...
There are 180 degrees on a straight line.

The length (distance) of a straight line always changes, the angle of a straight line is 180 degrees.
