3. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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.
