SYSTEMS OF POWER AND ROTATIONAL MOTION
Power for rotational motion is equally as important as power in linear motion and can be derived in a similar way as in linear motion when the force is a constant. The linear power when the force is a constant is P = →F⋅→v. If the net torque is constant over the angular displacement

GRAVITATION
1. movement, or a tendency to move, towards a centre of gravity, as in the falling of bodies to the earth. 2. movement towards or attraction to something.
Work Energy and Power
Work is done when a force produces motion. And for doing work energy is required. This energy we get from the food which we eat and if work is done by machine, then energy is supplied by fuels or by electricity.
Laws of Motion
Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration.
Internet of things
The Internet of Things, or IoT, refers to the billions of physical devices around the world that are now connected to the internet, all collecting and sharing data. Thanks to the arrival of super-cheap computer chips and the ubiquity of wireless networks, it's possible to turn anything, from something as small as a pill to something as big as an aeroplane, into a part of the IoT. Connecting up all these different objects and adding sensors to them adds a level of digital intelligence to devices that would be otherwise dumb, enabling them to communicate real-time data without involving a human being. The Internet of Things is making the fabric of the world around us more smarter and more responsive, merging the digital and physical universes.What is an example of an Internet of Things device?Pretty much any physical object can be transformed into an IoT device if it can be connected to the internet to be controlled or communicate information.A lightbulb that can be switched on using a smartphone app is an IoT device, as is a motion sensor or a smart thermostat in your office or a connected streetlight. An IoT device could be as fluffy as a child's toy or as serious as a driverless truck. Some larger objects may themselves be filled with many smaller IoT components, such as a jet engine that's now filled with thousands of sensors collecting and transmitting data back to make sure it is operating efficiently. At an even bigger scale, smart cities projects are filling entire regions with sensors to help us understand and control the environment.
Third sem Organic and Inorganic Chemistry
You can find some sample questions of organic and inorganic chemistry which is helpfull mainly for 3rd sem MG university aspirants.
Doppler Effect
The Doppler effect, or Doppler shift, describes the changes in frequency of any kind of sound or light wave produced by a moving source with respect to an observer. Waves emitted by an object traveling toward an observer get compressed — prompting a higher frequency — as the source approaches the observer.
Relation and Functions
An ordered pair is a set of inputs and outputs and represents a relationship between the two values. A relation is a set of inputs and outputs, and a function is a relation with one output for each input.
PRIDE AND PREJUDICE
Pride & Prejudice established the template for an infinity of romance novels, yet no subsequent love story has ever come close to equaling the delights of the original. ... He is madly in love, she can't bear him. In a scene both hilarious and dramatic, Elizabeth squashes Mr
WAVE OPTICS
In physics, physical optics, or wave optics, is the branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid.
UNITS AND MEASUREMENTS
Units of measure in the metric system include: The units of length or linear size are based on the metre. They include the kilometre (km) which is 1,000 metres, the centimetre (cm), and the millimetre (mm) which is 1/1,000th of a metre.
MOTION IN A PLANE
What is motion in a plane? Motion in a plane means motion in a two-dimensional plane which includes x-axis and y-axis.
