PHYSICS for class IX Syllabus
- Measurement and experimentation: common instruments like
Vernier caliper, micro-meter screw gauge for length, simple pendulum
for time. - Motion: uniform and non-uniform motion, motion in one dimension;
distance, displacement, speed, velocity, acceleration; scalar and vector
quantities; graphs of distance-time and speed-time; equations of
uniformly accelerated motion with derivations (graphical
representation). Uniform circular motion. - Laws of motion: Contact and non-contact forces; Relation between
force and motion; Newton’s first law of motion (qualitative
discussion); introduction to the ideas of inertia, mass and force.
Newton’s second law of motion including the mathematical
formulation (F=ma). Weight and mass. Newton’s third law of motion
(qualitative discussion); simple examples. Conservation of
momentum. - Gravitation: Kepler’s laws of planetary motion; acceleration due to
gravity; center of mass, idea of gravitational field. - Fluids: pressure in fluids; pressure and thrust; change of pressure
with depth (including the formula p=hρg); transmission of pressure in
liquids, atmospheric pressure; concepts of density, relative density
and specific gravity; buoyancy, Archimedes’ principle, principles of
floatation; determination of relative density of a solid. - Work and energy: types of energy, power, work energy relation,
transformation of energy; law of conservation of energy. - Heat: heat as a form of energy; concepts of heat and temperature;
anomalous expansion of water, graphs showing variation of volume
and density of water with temperature in the 0 to 10 deg C range;
Hope’s experiment and consequences of anomalous expansion.
Energy flow and its importance; energy sources. Global warming and
Green-house effect. - Sound: nature of sound waves, waves and wave motion; requirement
of a medium for sound waves to travel, propagation and speed in
different media; comparison with speed of light. Factors affecting
speed of sound; reflection of sound, echo, reverberation; infrasonic,
sonic and ultrasonic frequencies and their applications. - Light: reflection of light, images formed by a pair of parallel and
perpendicular plane mirrors; spherical mirrors, characteristics of
image formed by these mirrors; uses of concave and convex mirrors
(simple ray diagrams). - Electricity and Magnetism: simple electric circuit using an electric cell
and an electric bulb to introduce an idea of current (including its
relationship with charge); potential difference; insulators and
conductors; closed and open circuits; direction of current (electron
flow and conventional). Induced magnetism, magnetic field of earth;
neutral points in a magnetic field. Introduction to electromagnets and
its uses.
