direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre.[2][3] The mathematical description was derived in 1659 by Dutch physicist Christiaan Huygens. Isaac Newton’s description was:

When something spins around a single point it is called “circular motion”. B. We measure how fast something spins not in m/s (different points on the object are spinning at different velocities) but by measuring the angle described in a given time period. C. Angles can be measured in radians

this investigation‚ a mass was attached to a string and was swung horizontally for certain number of rotations (ten). The sole goal for this investigation was to find and verify the relationships between Centripetal Force‚ Frequency and Radius of circular path. In order to get relationships between the variables mentioned above‚ this experiment was divided into two parts. In Experiment A‚ the radius of the path (length of the string)‚ along with the mass was kept constant‚ and the relation between

Velocity is always tangent to the path in circular motion. Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration. In 1673‚ Christian Huygens‚ determined

The circular flow of income model is a theoretical representation of the economy. It shows the distribution of income within the economy and the interaction between the different sectors in a modern market economy. The five-sector model is a more elaborate model in comparison to the basic‚ two‚ three and four sector models. The model represents an economy like Australia and divides the economy into five main sectors. The first sector in the model is the Households sector. This sector refers to

Not only have vehicles changed‚ but the means by which people can get themselves to and from different locations has changed as well.

A carousel‚ or merry-go-round‚ is an amusement ride consisting of a rotating circular platform with seats for riders. The "seats" are traditionally in the form of rows of wooden horses or other animals mounted on posts‚ many of which are moved up and down by gearwork to simulate galloping to the accompaniment of looped circus music

centripetal acceleration. Centripetal force means “center seeking.” It is the force responsible for keeping an object in circular motion. If there were no centripetal force the object would fly off at a tangent because of Newton’s First Law. This is demonstrated by spinning an object on a string. If the string were to break or be cut‚ the object would fly out of its circular path at a tangent. An equation can be used to represent the relationship between centripetal force‚ mass‚ velocity‚ and

The concept of Circular Economy is to an increasing extent treated as a solution to series of challenges such as waste generation‚ resource scarcity and sustaining economic benefits. Environment and economy are closely related…however all these economic textbooks pay really less attention to the environment and in the best case scenario‚ a chapter illustrating how the economic theory can be applied to diverse environmental issues is added to them. Circular economy is touted as the practical solution
