Dynamics of Rotational Motions

Moment obrotowy
Moment obrotowy
Torque is an important quantity for describing the dynamics of a rotating rigid body. We see the application of torque in many ways in the world, such as ...

Równanie dynamiki obrotowej
Angular variables are introduced in rotational dynamics. Comparing the definitions of angular variables with the definitions of linear kinematic ...
Toczenie bez poślizgu
Toczenie bez poślizgu
People have observed the rolling motion without slipping ever since the invention of the wheel. For example, one can look at the interaction between a ...
Toczenie z poślizgiem
Toczenie z poślizgiem
Rolling with slipping is a physical phenomenon that occurs when a rolling object experiences both rotational and linear motion but also experiences ...

Praca i moc dla ruchu obrotowego
Work and power in rotational motion are completely analogous to work and power in translational motion. The total work done to rotate a rigid body through ...
Twierdzenie o energii pracy dla ruchu obrotowego
Twierdzenie o energii pracy dla ruchu obrotowego
The work-energy theorem for rotational motion is analogous to the work-energy theorem in translational motion. It states that the net work done by an ...

Moment pędu: Pojedyncza cząstka
Angular momentum is directed perpendicular to the plane of the rotation, and its magnitude depends on the choice of the origin. The perpendicular vector ...
Moment pędu: ciało sztywne
Moment pędu: ciało sztywne
The total angular momentum of a rigid body can be calculated using the summation of the angular momentum of all the tiny particles rotating in the same ...
Zasada zachowania momentu pędu
Zasada zachowania momentu pędu
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Considering a system that consists of n ...

Obrót asymetrycznego wierzchołka
By definition, a spherically symmetric body has the same moment of inertia about any axis passing through its center of mass. This situation changes if ...
Żyroskop
Żyroskop
A gyroscope is defined as a spinning disk in which the axis of rotation is free to assume any orientation. When spinning, the orientation of the spin axis ...
