FAQs on JEE Main 2015 April 11th Shift 1 Physics Question Paper with Answer Keys and Solutions
1. What is the weightage of Physics and Measurement and where can I find notes in the Vedantu app?
The weightage of Physics and Measurement is 4% and Physics, technology and society, SI units, Fundamental and derived units. The least count, accuracy, and precision of measuring instruments, Errors in measurement, Dimensions of Physical quantities, dimensional analysis, and its applications come under it. One can simply log into Vedantu’s app and search for physics question papers and can find answers there. One can also find notes with detailed solutions which are precise and easy to answer.
2. What will come under the Chapter Kinematics?
Kinematics weighs 3% in the entire paper and consists- The frame of reference. Motion in a straight line: Position-time graph, speed, and velocity. Uniform and non-uniform motion, average speed and instantaneous velocity Uniformly accelerated motion, velocity-time, position-time graphs, relations for uniformly accelerated motion. Scalars and Vectors, Vector addition and Subtraction, Zero Vector, Scalar and Vector products, Unit Vector, Resolution of a Vector. Relative Velocity, Motion in a plane. Projectile Motion, Uniform Circular Motion. Vedantu provides you with top results and study material on these topics.
3. Are Oscillations and Waves important in Physics when preparing for IIT JEE?
Oscillations and Waves weigh 3% and are hence important. It consists of Periodic motion - period, frequency, displacement as a function of time. Periodic functions. Simple harmonic motion (S.H.M.) and its equation; phase; oscillations of a spring -restoring force and force constant; energy in S.H.M. - Kinetic and potential energies; Simple pendulum - derivation of expression for its time period; Free, forced and damped oscillations, resonance.
Wave motion. Longitudinal and transverse waves, speed of a wave. Displacement relation for a progressive wave. Principle of superposition of waves, a reflection of waves, Standing waves in strings and organ pipes, fundamental mode and harmonics, Beats, Doppler effect in sound.
4. Does Optics cover the major part of the paper?
Yes, it holds 10% weightage and consists of General Concepts used in Geometrical Optics, Reflection of Light, Reflection from a Spherical Surface, Refraction of Light and Refractive index of Medium, Law of Refraction, Single Refraction from Plane Surface, Shift due to a Glass Slab, Refraction from Spherical Surface, Lens Theory, Total Internal Reflection, Refraction through Prism, Deviation, Optical Instruments.
