Yes, flipping a pancake involves a rigid motion. When you flip it, the pancake rotates around an axis, but its shape, size, and orientation remain unchanged throughout the motion. This means that all points of the pancake maintain their relative positions to one another, characteristic of rigid motion.
The best way to flip pancakes using a pancake spatula is to slide the spatula underneath the pancake, lift it slightly, and then quickly and confidently flip it over in one smooth motion.
When you flip a pancake, several muscle groups are engaged to perform the action. Primarily, your arm and shoulder muscles, such as the deltoids and biceps, work to lift and rotate the spatula. Additionally, core muscles stabilize your body and maintain balance during the motion. This coordinated effort allows you to effectively flip the pancake with precision.
To flip a pancake, you primarily use the muscles in your forearm and wrist, specifically the flexor and extensor muscles that control wrist movements. Additionally, the shoulder and upper arm muscles, such as the deltoids and biceps, help lift and maneuver the spatula or frying pan. Engaging your core muscles can also provide stability during the motion.
This is an interesting example. It has what is known as an implied subject. This sentence is an instruction which is addressed to you. If we were to write it out in full, it would say "You should flip the pancake when the edges are brown" (which, incidentally, is true). The subject of that sentence is you. Pancake is the object. And "when the edges are brown" is an adverbial phrase, which modifies the verb flip.
It's a spatula, a flat plate on the end of a stick, which you can slide under a pancake and flip it over.
You better flip those pancakes or they're gonna burn.
Movement of a shape can involve flexing - for example, a square frame being flexed into a rhombus. Rigid motion excludes such motion: the shape of the moving object does not change.

A rigid motion transformation is one that preserves distances and angles between points in a geometric shape. Anything that involves changing the size or shape of the object, such as scaling or shearing, would not describe a rigid motion transformation.
The term "flip" can be paired with several words depending on the context. In sports, you might hear "flip" used with "trick" in skateboarding or gymnastics. In cooking, "flip" often goes with "pancake" or "burger." Additionally, in finance, "flip" can refer to "property" in the context of real estate investments.
The key difference between a particle and a rigid body is that a particle can undergo only translational motion whereas a rigid body can undergo both translational and rotational motion
