Fizika 10 Miakishev Konspekt Uroka Po Teme Statika [2026 Edition]

(Clockwise moments are usually considered negative, and counter-clockwise moments positive).

The point through which the resultant of all gravitational forces acting on the particles of the body passes, regardless of the body's orientation. For simple geometric shapes made of uniform material, it coincides with the geometric center.

Statics is the branch of mechanics that studies the conditions for the equilibrium of bodies. Equilibrium is a state where a body remains at rest or moves uniformly and rectilinearly relative to a chosen inertial frame of reference. 2. Key Concepts fizika 10 miakishev konspekt uroka po teme statika

If displaced slightly, the body returns to its original position (the center of gravity rises).

The vector sum of all external forces acting on the body must be zero. Statics is the branch of mechanics that studies

An idealized model of a body where the distance between any two of its points remains constant, regardless of the forces applied.

To ensure a body does not move translationally or rotate, two conditions must be met simultaneously: Key Concepts If displaced slightly, the body returns
