An object is said to be in state of motion if its position changes with the passage of time. If the position of the object does not change with the passage of time then the object is said to be at rest. We have now define what is motion and to describe it we consider simplest form of motion that is motion of any object in one dimension for example car moving on the road. To determine the position of car at different times , we could measure its distance from starting point and record all these observations. These observations can be recorded in form of a table or we can draw a distance versus time graph for the motion of the car and see how it is moving.
The acceleration vector has the same direction as instantanous change in velocity. Since the direction of the velocity changes in the direction in which the curve bends ,the acceleration is always pointing towards concavity of the curve
The acceleration in curvilinear motion can also be expressed in terms of two components
We all know that Gauss’s law is basically the relation between the charge distribution producing the electrostatic field to the behaviour of electrostatic field in space. Also Gauss’s law is based on the fact that flux through any closed surface is a measure of total amount of charge inside that surface and any charge outside that surface would not contribute anything to the total flux.
Find your own deep and compelling reason to successfully learn your subject and pass your exams. Plan your time to include study, revision and social commitments – a balance of having fun, taking breaks and studying is vital. Use multi-coloured Mind Maps for your notes.
There are less then two weeks remaining before your board exams start and it is the high time students should concentrate and revise what they have studied over the past year. Students should manage their time so that they can divide their time for revising different subjects.
Examination time is the time when you are busy most of your time doing nothing but studying hard round the clock even in night so that you can score good marks in your exams and get promoted to new class. Although it is important to study hard during your exams but you should not let exam pressure take over you and you should not feel stressed during your exam days. Do not feel anxius and remember that at the end of the day, it is after all just an exam!
