Z notes physics

Radian: one radian is the angle subtended at the center of the circle by an arc of length equal to the radius of the circle. A body moving in a circle at a constant speed changes velocity since its direction changes. Thus, it is accelerating and hence experiences a force.

Centripetal force: resultant force acting on an object moving in a circle, always directed towards the center of the circle perpendicular to the velocity of the object. A mass M M M is placed on the plate, a distance d d d35cm, from the axis of rotation.

The speed of rotation is increased from zero until the mass slides off the plate. The maximum frictional force F F F between the plate and the mass is given by the expression. Determine the maximum number of revolutions of per minute for the mass M M M to remain on the plate.

The centripetal force on the particle is the frictional force so the max speed is when friction is at max. For an isolated point mass, the gravitational field is spherical in shape with the mass at the center.

The gravitational field is described by the field lines. A field line is the path followed by a free unit mass in that gravitational field. The time taken for one orbit is 3. Gravitational potential energy of a mass m m m at a point in the gravitational field of another mass M M Mis the work done in bringing that mass m m m from infinity to that point.

Geostationary satellite is one which always appears to be above a certain point on the Earth. However, mass of the satellite not fixed hence the k. The Earth may be considered to be a sphere of radius 6. A satellite of mass kg is to be launched from the Equator and put into geostationary orbit. Show that the radius of the geostationary orbit is 4. This sensation is because. The sensation of weight reaction force is the difference between F G and F C which is zero.

A mole: amount of substance containing same number of particles as in 12g of carbonThe Cambridge IGCSE Physics syllabus helps learners to understand the technological world in which they live, and take an informed interest in science and scientific developments. They learn about the basic principles of Physics through a mix of theoretical and practical studies. Learners also develop an understanding of the scientific skills essential for further study at Cambridge International A Level, skills which are useful in everyday life.

As they progress, learners gain an understanding of how science is studied and practiced, and become aware that the results of scientific research can have both good and bad effects on individuals, communities and the environment.

Formula Sheets. Misc Notes.SI Units: The International System of Units is one of the most widely used system for taking and recording measurements. Prefixes: Sometimes a physical quantity is too big or too small to be conveniently expressed in basic units. Then prefixes are used.

These are multiples or decimals of ten. Distance: It is defined as the total path length taken between two points. It is a scaler quantity. Its SI Unit is metre, m. Displacement: It is defined as the change of position of a point in a particular direction. It is a Vector quantity as it has both magnitude …. Force: A force is a pull or push that one object exerts on another which produces or tends to produce a motion, stops or tends to stop a motion.

Mass: Mass is the measure of amount of substance in a body. Irrespective of its shape, location and speed. Mass depends on the number and composition of atoms and molecules. SI unit: kilogram kg Remember: mass is a scalar quantity. Moments: The moment of a force is the product of the force and the perpendicular distance from the pivot to the line of action of the force. Pressure is defined as the force acting per unit area.

While calculating pressure in liquids height …. Work: Work done by a constant force is given by the product of the force and the distance moved in the direction of the force. Remember: Work is not done when The direction of the …. December 23, Igcse Physics Revision Notes Thermal energy always flows from a region of higher concentration to a region of lower temperature. Conduction: Conduction is the process of thermal energy transfer without any flow of the material medium Conduction occurs mostly from solid to solid due to molecular vibration.

Motion in a Circle

Where can I get the book of physics in soft copy. The link is down. Dearest apologies. While I fix the problem, you can access the notes from the direct link above. Thank You. Physics file there is an issue!There are two questions in each paper.

Outline: it requires candidate to collect data, plot a graph and draw simple conclusions. Outline: No graph will be required. There are only 2 marks of quality on whole paper.

In this question, first set up the apparatus in exactly the same manner as shown on the question paper. The first part of this question usually involves measuring something like diameter of a wire, length of some part of experiment apparatus, potential difference, current etc. Click here to see the animation. Also remember to add appropriate units along with the individual readings you measure. Then it says to repeat the procedure and get six different sets of data in a table.

Largest possible range is required. These values of L you have cover almost the whole range of values possible from minimum to maximum. Same applies if you have set of resistors and you are asked to make different combinations of resistors to yield different values of resistances.

These values of resistance must cover the whole range possible, like from minimum to maximum value possible here keeping the difference between individual values of resistance for different combinations common is not necessary! You will draw one single table with headings. The data must be up to to the same precision. All the raw readings of a particular quantity should be recorded to the same number of decimal places which should in turn be consistent with the precision of the measuring instrument.

For example, you record the values for current I using the ammeter. These number of significant figures for calculated quantity should be kept same throught out the colum for that quantity. However, if you are to calculate resistance from p. Then the number of sf in the calculated quantity must be equal to the least number of sf used in the calculation or one better. Therefore, the resistance calculated can only be given to either 2 sf least sf used in calculation or 3 sf 1 better sf.

Use the full space provided. Then draw a narrow column headed, S. Finally, record your raw data in to the table which is obtained from the experimental procedure. Afterwards, use this data to calculate other quantities. Just kidding.The syllabus includes the main theoretical concepts which are fundamental to the subject, a section on some current applications of physics, and a strong emphasis on advanced practical skills. Practical skills are assessed in a timetabled practical examination.

The emphasis throughout is on the understanding of concepts and the application of physics ideas in novel contexts as well as on the acquisition of knowledge.

Please note that the Scheme of Assessment has changed since I hope you find them useful. In addition, your name will be written in the credits section of this post. Really helped me in getting an A in physics. Please tell me from where I can get physics A2 notes? Is it possible to enable free download again please? Thank you very much! Hello Thanks. Do you have any notes on Particles Physics? And doppler effect? Very nice collectionit will be more better if you collect old questions and their answers in one folder for physics.

I need answers for SHM under that category. Can I please have phys chem bio notes and questions topically? It will be easy for us to do seperately. Please help! Assalam o alaikum Pakistan main A levels kin boards say hota hay. A levels pre-medical main jo physics hay uska code kia hay. I am very sorry but you will need to check the answers from the respective mark schemes. Kindly add a link to the mark scheme ASAP, it would be big help.

Kindly make do with the past paper years written after every question and check from respective mark schemes. Or maybe google Sajit Chandra Shakya and contact him for answers, he compiled these questions.

These notes will surely help but their effectiveness varies from person to person. Definitely keep the copy of the syllabus around when using these notes. Thanks a lot for informing us. We have posted an alternative link until we figure out the solution to the problem. The current website has been facing problems with Dropbox.
