Circular Motion

 


Circular Motion is defined as the movement of an object along circumference of a circle. Some examples of circular motion are motion of moon around the earth, motion of a satellite in a circular orbit around the earth and motion of a cyclist on a circular tract etc.
In last episode, we talked about acceleration. We learnt that change in velocity per unit time is known as acceleration. Now let's take a step ahead and find out on what factors change in velocity depends. From our previous episodes we know that velocity does not only depends on magnitude of speed, but it also depends on the direction of motion. That suggests that there are three ways to make change in velocity.

  • If direction is kept constant and magnitude of speed is changed, velocity will change.
  • If magnitude of speed is kept constant and direction is changed, velocity will change.
  • and if magnitude of speed and direction are changed, velocity will change.

 

In a circular path, direction of motion changes at every point on the circle. Hence when an object moves on a circular track. Its direction keeps changing at every moment that makes a constant change in its velocity. That is why a circular motion is also known as accelerated motion. This accelerated motion is also subdivided into two categories.

  • Uniform circular motion
  • Non-uniform circular motion

 

When an object moves in a circular path with uniform speed, its motion is called uniform circular motion.
Similarly, when an object moves in a circular path with non-uniform speed, its motion is called non-uniform circular motion.

Organic Compounds

  Organic compounds and their differences form inorganic compounds Organic compounds are compounds that contain carbon atoms bonded with other elements such as hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), and halogens (such as chlorine and bromine). They form the basis of organic chemistry, which is the study of carbon-containing compounds. The key characteristic that sets organic compounds apart from inorganic compounds is the presence of carbon. Carbon has a unique ability to form strong covalent bonds with other carbon atoms and a wide range of other elements, resulting in a vast number of organic compounds with diverse structures and properties. In contrast, inorganic compounds are typically derived from minerals and do not contain carbon-hydrogen (C-H) bonds. Inorganic compounds can still contain carbon, but they often have a different composition and bonding pattern than organic compounds. Examples of inorganic compounds include minerals, salts, metals, and nonme...

Electric Potential - An Overview of History, Definition and Applications.

  Brief history of Electric Potential 1. Ancient Static Electricity: The concept of electric potential began with the ancient Greeks, around 600 BCE. They observed static electricity phenomena, like the attractive properties of amber after rubbing it against fur. This laid the groundwork for later understandings. 2. Gilbert and Magnetic Potential: In the late 16th century, William Gilbert expanded our understanding of electric potential by exploring magnetic phenomena. His work set the stage for the connection between electricity and magnetism. 3. Volta's Pioneering Voltaic Pile: The late 18th century witnessed significant strides. Alessandro Volta's invention of the voltaic pile in 1800 was a turning point. This early battery produced a stable electric current, showcasing the potential to control and utilize electric power. 4. Ohm's Law and Resistance: In 1827, Georg Simon Ohm formulated Ohm's Law, which describes the relationship between electric poten...

Buoyancy Force and Archimedes’ principle

Buoyancy Force Buoyancy, or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object.   We have come across many daily life observations of sinking objects in water and floating on it. As boats, ships , plastic bottles and straws float on the surface of water, some fruits, iron pieces and stones etc. don't float on the water. We have also experienced that, when we try to sink tightly capped empty bottles in water, it forces it up towards the surface. We have also experienced that; a heavy piece of brick or iron feels lighter inside water than outside. Although! Humans discovered this long ago in history. But the net amount of force exerted by water on any object was still a mystery. Until Archimedes figured it out in 246 BC.   Archimedes’ principle Archimedes observed that, when we sink any object in a completely filled vessel with water, it displaces some water. He also calculated that; the net buoyancy force ...
