Lifting wieghts
Rolling motions of the foot are described as inversion (rolling with the big toe initially lifting upward) and eversion (rolling with the big toe initially moving downward).
Peristalsis is strictly mechanical. If you think of pedaling a bicycle up and down small rolling hills, that is like the mechanical action of peristalsis. It keeps pushing foodstuffs forward--even when you become constipated, the muscles will still try to keep 'pedaling'. Chemical action involves enzymes or bile.

The functions of a mechanical department include maintaining the rolling stock including freight wagon, passenger coaches, cranes and DMUs. It formulates plan for procurement of machinery, rolling stock and ensures safety.

enery can be divide into 2 classes 1. is mechanical energy-- this is the energy required to do work. Examples would be the rolling of a wheel, lifting a weight and energy that uses simple machiines (or a bunch of simple machines put together to make a more complicated design or arrangement.) 2. is potential energy-- this is "stored" energy like the heat released in burning a fuel (aka: chemical energy), or the energy of position such as a swing at the top of it's pendulum swing.
When the object is rolling it has kinetic energy or KE and when the object is at rest it has potential energy or U. In this case both are mechanical energies and mechanical energy is conserved within a system meaning it is only transferred not gained or lost.
The process is made mechanically using a foil rolling mill.
The same type as is done when pushing, shoving, rolling, lifting, wiggling etc. ... a force acting through a distance.
It's just a slangy way of saying "let's get started." The image is of a ball game and you're starting the game by rolling out the ball. You can also "keep the ball rolling" by continuing whatever you're doing.
