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.
A cone-shaped object will not roll in a straight line because the circumference of the cone changes from one end to the other. For example, if one end of the cone has a circumference of 10 inches, that end will travel 10 inches per revolution, but if the other end of the cone has a 2 inch circumference, it will only travel 2 inches per revolution.
The word straight does have an antonym, which is crooked. So perhaps a crooked line is the opposite of a straight line.
The length (distance) of a straight line always changes, the angle of a straight line is 180 degrees.
Well, honey, a cone can't roll in a straight line because of its shape. It's like asking a square to roll smoothly without wobbling. Physics just ain't gonna let that happen, sweetie. So, in short, no, a cone can't roll in a straight line.
a cylinder
On a smooth level surface, and with no forces acting on it after the moment of release, it MUST.

Every where. Roll a ball on the floor. As soon as it leaves your hand it continues to roll in a straight line. The outside force, friction slows it down. A rock can sit on the ground for a long time until an outside force from someone picks up he rock, or kicks it. Shoot an arrow thru the air. It would continue in a straight line if gravity did not pull it down to earth.
The straight-line distance is 1,030 miles (to the coastline of Puerto Rico). This is the true straight line distance which accounts for the curvature of the earth, NOT simply a straight line drawn on a map.

The ailerons, which act in opposite directions, are used to roll the aircraft while in straight line flight, and also to assist in turns, when used with rudder.
it just a straight line
