Can anybody please explain to me the concept of rotational motion?? I'm so lost in that chapter... ><
Rotational motion is the movement of an object around an axis or pivot point.
Some examples of rotational motion include the spinning of a top, the rotation of the Earth on its axis, and the movement of a Ferris wheel.
Rotational motion involves movement around an axis, while linear motion involves movement in a straight line.
Angular velocity is the rate of change of the angle of rotation, while linear velocity is the rate of change of the position of an object in a straight line.
The moment of inertia is calculated by multiplying the mass of an object by the square of its distance from the axis of rotation.
