SCIENCE (52) PHYSICS SCIENCE Paper - 1 Aims: 1. To acquire knowledge and understanding of the terms, facts, concepts, definitions, laws, principles and processes of Physics. 2. To develop skills in practical aspects of handling apparatus, recording observations and in drawing diagrams, graphs, etc. 3. To develop instrumental, communication, deductive and problem-solving skills. There will be one paper of two hours duration carrying 80 marks and Internal Assessment of practical work carrying 20 marks. The paper will be divided into two sections, Section I (40 marks) and Section II (40 marks). Section I (compulsory) will contain short answer questions on the entire syllabus. Section II will contain six questions. Candidates will be required to answer any four of these six questions. Note: Unless otherwise specified, only SI Units are to be used while teaching and learning, as well as for answering questions. 2. Motion in One Dimension Scalar and vector quantities, distance, speed, velocity, acceleration; graphs of distance-time and speed-time; equations of uniformly accelerated motion with derivations. Examples of Scalar and vector quantities only, rest and motion in one dimension; distance and displacement; speed and velocity; acceleration and retardation; distance-time and velocity-time graphs; meaning of slope of the graphs; [Nonuniform acceleration excluded]. 4. To discover that there is a living and growing physics relevant to the modern age in which we live. CLASS IX Equations to be derived: v = u + at; S = ut + at2; S = (u+v)t; v2 = u2 + 2aS. [Equation for Snth is not included]. 1. Measurements and Experimentation (i) International System of Units, the required SI units with correct symbols are given at the end of this syllabus. Other commonly used system of units - fps and cgs. Simple numerical problems. 3. Laws of Motion (i) Contact and non-contact forces; cgs & SI units. Examples of contact forces (frictional force, normal reaction force, tension force as applied through strings and force exerted during collision) and non-contact forces (gravitational, electric and magnetic). General properties of non-contact forces. cgs and SI units of force and their relation with Gravitational units. (ii) Newton s First Law of Motion (qualitative discussion) introduction of the idea of inertia, mass and force. Newton's first law; statement and qualitative discussion; definitions of inertia and force from first law, examples of inertia as illustration of first law. (Inertial mass not included). (ii) Measurements using common instruments, Vernier callipers and micro-metre screw gauge for length, and simple pendulum for time. Measurement of length using, Vernier callipers and micro-metre screw gauge. Decreasing least-count leads to an increase in accuracy; least-count (LC) of Vernier callipers and screw gauge), zero error (basic idea), (no numerical problems on callipers and screw gauge), simple pendulum; time period, frequency, graph of length l versus T2 only; slope of the graph. Formula T=2. . l g [no derivation]. problems. Only simple numerical 97
