    Study Notes

    Motion

    • Motion of a car or cycle wheels is a combination of translational and rotational motion.
    • Rotational motion is also called 'rolling motion'.

    Periodic Motion

    • A motion that occurs when an object moves in a repeated pattern (a cycle) over equal periods of time is called a periodic motion.
    • Examples: motion of a pendulum, rotational motion of Earth, revolution of Earth around the Sun.

    Oscillatory Motion

    • A motion that occurs when an object moves to and fro about its mean position over equal periods of time is called an oscillatory motion or vibratory motion.
    • Examples: motion of a simple pendulum, motion of a vibrating stretched string, motion of an oscillating spring.
    • The term 'vibratory motion' is used when an object oscillates very fast.

    Distance

    • Distance is the length of the actual path between initial and final positions of a particle.
    • Distance is a scalar quantity.
    • Distance depends on the path.
    • Distance never decreases with time.
    • Distance is always taken positive.
    • Unit: C.G.S. system - centimeter (cm); S.I. system - metre (m).
    • Odometer of a vehicle measures the distance.
    • Distance is greater than displacement on a curved path.
    • Distance is exactly equal to displacement when it follows a straight path without changing its direction.

    Displacement

    • Displacement is the shortest distance between initial and final positions of a particle.
    • Displacement can be negative.
    • Unit: same as distance.

    Number Line

    • Integers can be represented on a number line.
    • The number line shows that every integer has an opposite number except '0'.
    • The numbers +1, +2, +3..... are positive numbers, denoted by +Z.
    • The numbers –1, –2, –3..... are negative numbers, denoted by –Z.
    • The positive and negative integers together with 0 are integers, denoted by Z or I.

    Speed

    • Speed gives no idea about the direction of motion of the object.
    • Speed can never be negative; in motion, it is taken positive; at rest, it is zero.
    • Unit: C.G.S. system - centimeter/second (cm/s); S.I. system - metre/second (m/s).
    • 1 km/h = 5/18 m/s.
