Motion

This document discusses different types of motion including linear, circular, rotational, and vibratory motion. It defines concepts like rest and motion using a frame of reference. The document also covers 1D, 2D and 3D motion with examples. It distinguishes between scalar and vector quantities and discusses types of vectors and how they can be added.

TEACHING COMPETENCY LEVEL II BY, B. NANCY DIANA, 1122119BD094.
MOTION • A CHANGE IN POSITION OF AN OBJECT OVER TIME IS KNOWN AS MOTION.
CONCEPT OF REST AND MOTION • Concept of rest and motion represented by a frame of reference. • Frame of reference
TYPES OF MOTION • THERE ARE FOUR TYPES i)LINEAR MOTION ii) CIRCULAR MOTION iii) ROTATIONAL MOTION iv)VIBRATORY MOTION
LINEAR MOTION • An object moves in a straight line is known as linear motion.
EXAMPLES
CIRCULAR MOTION An object moves in a circular path
EXAMPLES I)Rotation of clock ii)Rotation of earth iii)Roation of fan
VIBRATORY MOTION If an object or particle executes to and fro motion about a fixed point , it is said to be in vibratory motion.
EXAMPLE • The stretched string • The motion of the swing • Simple pendulum
OSCILLATORY M0TION
SIMPLE PENDULUM
MOTION IN ONE DIMENSION • It is the motion of the particle moving along the straight line. • Example: • Motion of a train along the straight railway track. • An object falling freely under gravity.
MOTION IN TWO DIMENSION • If a particle moving along a curved path in a plane then it is said to be in two dimensional motion. • Example: • Motion of a carrom coin.
MOTION IN THREE DIMENSION • A particle moving in a usual three dimensional space has three dimensional motion. • Example : •A bird flying in the sky. •Random motion of a gas molecule.
SCALAR AND VECTOR SCALAR • It is a property which can be described only by magnitude. VECTOR • It is a quantity which described by both magnitude and direction.
TYPES OF VECTORS • Equal vectors • Collinear vectors • Orthigonal vectors
