3. Kinematics
Kinematics is the
branch of PHYSICS that
describes the MOTION
of points, bodies
(objects) and systems of
bodies (groups of
objects) without
consideration of the
causes of motion.
The study
of kinematics is often
referred to as
the geometry of motion
4. What is
motion??
?
When a body is
continuously changes
its
Position , then the
body is said to be in
motion.
TYPES OF MOTION
.LINEAR MOTION
.ANGULAR MOTION
.GENERAL MOTION
.PROJECTILE MOTION
.UNIFORM MOTION
.NON-UNIFORM
MOTION
5. Linear
Motion
Motion that occurs in a
straight line.All parts of a
body move in a same
direction and with same
speed
Eg.
An athlete running on a
straight track
6. Angular
Motion
When a body moves
round and round on its
axis , then it is said to be
in angular motion.
Eg.
A rotating fan , earth , a
spinning top……
7. General
Motion
It is the most common
form of motion , as most
human movement
requires the rotation of a
body parts around
joints.
Eg.
Cyclist uses several
angular motions to
produce linear motion of
bicycle.
8. Projectil
e Motion
When a object is thrown
it becomes a projectile
and is influenced by
gravity , air , speed , etc.
Eg.
Rugby ball , shuttle coxs
etc.
9. Non-Uniform
Motion
If an object covers
unequal distance in
equal time of interval is
said to be as non
uniform motion.
Eg.
A person jogging , a car
moving in a crowded
place , a bowler
throwing a ball , etc
10. Uniform
Motion
If a body covers equal
distance in equal
intervals of time then it
is said to be as uniform
motion.
Eg.
Needles of a watch , a
fan moving at a constant
speed
11. Uniform-
Acceleration
Deceleration
If a bodies velocity
increases with equal
interval of time with equal
amount.
If a bodies velocity decreases
with equal interval of time
with equal.
12. Speed , Height
and Angle of
release
Different angle of release
affects the distance
travelled and the height
attained by an object.
When a ball is released
from a ground level , the
optimal angle for release
for maximum distance is
about 45 degrees.
13. Related Terms
GRAVITATIONAL FORCE- Body attracted with some or the force.
ELECTRO MAGNET FORCE- Forces due to electricity or magnet.
NUCLEAR FORCES-Forces inside the nucleus.
WEAK FORCES-Forces between rays.
PATH LENGTH-Travelled path is called trajectory and total length
covered is path length.
DISTANCE-Length of path covered by a body. UNIT- Metre(m)
DISPLACEMENT-Shortest distance between final and initial point.
INITIAL POINT-Starting point.
FINAL POINT-End point.
14. POINT OBJECT-Distance travelled is much greater than its own size.
PHYSICAL QUANTITIES-Quantities used to describe motion of a
body. They are of types-SCALAR & VECTOR.
SCALAR-They have only magnitude.
VECTOR-They have magnitude as well as direction.
SPEED-Rate of change of velocity.
INSTANTANEOUS SPEED-Speed of body at a particular instant of
time.
AVERAGE SPEED-Ratio of total distance travelled to total time taken.
VELOCITY-Rate of change of displacement.
ACCELERATION-Rate of change of velocity.
