การเคลื่อนที่แบบหมุนthanakit5531. The document discusses circular motion and kinematic equations relating displacement, velocity, acceleration, and other variables. It defines relationships between angular displacement, angular velocity, linear velocity, tangential acceleration, and angular acceleration.
2. Equations are provided relating angular displacement to angular velocity and time, linear velocity to angular velocity and radius, and tangential acceleration to angular acceleration and radius.
3. The kinematic relationships for circular motion allow one to calculate variables like velocity, acceleration, and displacement given information about rotation, radius, and time.
งาȨละพลังงานthanakit5531) The document discusses work (W) in physics and defines it as the product of an applied force (F) and the distance (s) over which it acts (W=Fs).
2) Several examples are provided to demonstrate calculating work done by various constant and non-constant forces.
3) The concept of net work is introduced as the sum of individual works done by each force acting on an object.
