An object moving in a straight line (having linear momentum) can have angular momentum. For example, let’s say we throw a ball at one end of a stick (see Figure 1). The stick can pivot around point O. When the ball hits the stick, the stick rotates. If the system of the ball and stick has […]

## Rotational Kinematics Numerical Problems and solutions

This post is all about Rotational Kinematics Numerical Problems and solutions. We will use the following four rotational kinematic equations (presented together with their translational counterparts) to solve the numerical problems. Rotational kinematic equations | equations used to solve rotational motion numerical In these equations, the subscript 0 denotes initial values (ω0 and vo are initial values). […]

## 3 Important Relationships between Circular Motion and Linear Motion Quantities

In this post, we will focus on the definitions of circular motion and linear motion first which will show their basic differences as well. In addition to this, we’ll derive a couple of important relationships between the quantities of circular motion and linear motion. We will derive the following:a) Relationship between angular displacement and linear displacement […]
