Examples of Circular in the following topics:

  • Overview of Non-Uniform Circular Motion

    • Non-uniform circular motion denotes a change in the speed of a particle moving along a circular path.
    • What do we mean by non-uniform circular motion?
    • The answer lies in the definition of uniform circular motion, which is a circular motion with constant speed.
    • It follows then that non-uniform circular motion denotes a change in the speed of the particle moving along the circular path.
    • This means that the radius of the circular path is variable, unlike the case of uniform circular motion.

  • The Circular Flow Model

    • The basic circular flow model consists of two sectors that determine income, expenditure, and output.
    • The factor owners spend the income on goods which leads to the circular flow of payments .
    • This circular flow is ongoing between households and firms.
    • The circular flow model shows the flow of payments between households and firms.
    • State the function of the circular flow diagram and the production possibilities frontier

  • Circular Motion

    • Uniform circular motion describes the motion of an object along a circle or a circular arc at constant speed.
    • Therefore, uniform circular motion indicates the presence of a net external force.
    • The direction of the velocity along the circular trajectory is tangential.
    • The equation for the acceleration $a$ required to sustain uniform circular motion is:
    • In uniform circular motion, the centripetal force is perpendicular to the velocity.

  • The Circular Flow and GDP

    • In economics, the "circular flow" diagram is a simple explanatory tool of how the major elements in an economy interact with one another.
    • The continuous flow of production, income and expenditure is known as circular flow of income.
    • It is circular because it has neither any beginning nor an end.
    • The circular flow involves two basic assumptions:
    • The circular flow is a simplified view of the economy that provides an ability to assess GDP at a specific point in time.

  • Kinematics of UCM

    • Uniform circular motion is a motion in a circular path at constant speed.
    • Under uniform circular motion, angular and linear quantities have simple relations.
    • When objects rotate about some axis, each point in the object follows a circular arc.
    • Under uniform circular motion, the angular velocity is constant.
    • Any net force causing uniform circular motion is called a centripetal force.

  • Simple Harmonic Motion and Uniform Circular Motion

    • Uniform circular motion describes the motion of a body traversing a circular path at constant speed.
    • Displacement around a circular path is often given in terms of an angle θ.
    • The acceleration in uniform circular motion is always directed inward and is given by:
    • A point P moving on a circular path with a constant angular velocity ω is undergoing uniform circular motion.
    • Describe relationship between the simple harmonic motion and uniform circular motion

  • Centripetal Force

    • A force which causes motion in a curved path is called a centripetal force (uniform circular motion is an example of centripetal force).
    • Uniform circular motion is an example of centripetal force in action.
    • Because the object is moving perpendicular to the force, the path followed by the object is a circular one.
    • It is this force that keeps a ball from falling out of a bucket if you swing it in circular continuously.
    • Angular velocity is the measure of how fast an object is traversing the circular path.

  • Chromosomes and DNA Replication in the Archaea

    • Archaea usually have a single circular chromosome, the size of which may be as great as 5,751,492 base pairs in Methanosarcina acetivorans, which boasts the largest known archaean genome.
    • Archaea typically have a single circular chromosome.
    • The circular chromosomes contain multiple origins of replication, using DNA polymerases that resemble eukaryotic enzymes.
    • The replication of DNA, beginning at the origins of replication present on the circular chromosomes, requires initiator proteins.
    • The recruitment of additional proteins by way of the initiator proteins allows the separation of the circular DNA and results in the formation of a bubble.

  • Circular Motion

    • Magnetic forces can cause charged particles to move in circular or spiral paths.
    • Particle accelerators keep protons following circular paths with magnetic force.
    • So, does the magnetic force cause circular motion?
    • This is typical of uniform circular motion.
    • Uniform circular motion results.

  • Relationship Between Linear and Rotational Quantitues

    • For example, consider the case of uniform circular motion.
    • This is the first advantage of describing uniform circular motion in terms of angular velocity.
    • For simplicity, let's consider a uniform circular motion.
    • Because $\frac{dr}{dt} = 0$ for a uniform circular motion, we get $v = \omega r$.
    • Each particle constituting the body executes a uniform circular motion about the fixed axis.
