弧长公式(二)（Formula of arc length (two)）Formula of arc length (two)Tsinghua middle school Li Na Teaching target:1. make students flexibly apply arc length formula to solve related problems 2., to further develop students' ability to abstract mathematical models from practical problems, and ...
Everywhere you turn, there are rotations. The most prevalent example isthe earth, which revolves around an axis. An example of a transformation is a rotation, which revolves a figure around a point. The shape and dimensions of a figure remain the same while facing in a different direction. ...
for rotation through its central axis. What will be the moment of inertia of the sphere, if the rotation axis is changed to pass through a point on its surface? Answer:If the rotation axis is changed from the center axis of the sphere to an axis that connects to the surface of the sp...
Suppose we move a point Q given by the coordinates (x, y, z) about the x-axis to a new position given by (x', y,' z'). The x component of the point remains the same. Hence, this rotation is analogous to a 2D rotation in the y-z plane. For this reason our 3 x 3 ...
Consider a particle mass, m revolving around a fixed point. The particle is attached to a rod of negligible mass with length, r. To make the particle rotate, a force is exerted perpendicular to the radius or length of the rod — a quantity called torque. Torque quantifies the turning or...

Measuring the Angle of Rotation In angle measurement, the initial side is always at the positive x-axis. The center of rotation, the vertex, pivots at the point shared by the two rays. One complete cycle is like going around in a full circle. The terminal side will end at the same pos...
Rigid body around a point of rotating inertia inertia tensor described by more general. The two order tensor of inertia tensor is complete, it characterizes by the size of the moment of inertia of rigid body around the axis of any point. Add a detailed explanation of the moment of inertia ...

A geometric figure on a coordinate plane is dilated around a center of dilation, which is a fixed point on the plane used to scale the dilation. When a figure is plotted on a coordinate plane, the coordinates of the pre-image can be multiplied by the same number to find the coordinates...
