The team’s orb rolled vertically at a rate of about 0.5 millimeters per second. Regardless, Mitra and colleagues wrote that their observation “challenges our basic understanding of physics,” with ...

Before looking at rolling objects, let's look at a non-rolling object. Suppose that I have some frictionless block on an inclined plane. The block can only accelerate in the direction along the plane.

For example, they showed how the time period of rolling diverges, or increases to infinity, near the transition, and how the system settles into a stable rolling motion away from the critical point.

Rolling objects have played key roles in technology since at least the advent of the wheel. Most rolling objects used by humans are cylindrical, spherical or conical. The first two shapes are useful ...

For a rolling object, kinetic energy is split into two types: ... that you can roll down the ramp. For example, rolls of tape, markers, plastic bottles, different types of balls, etcetera.

For example, they showed how the time period of rolling diverges, or increases to infinity, near the transition, and how the system settles into a stable rolling motion away from the critical point.
