Q.1. Identify the types of motion.<\/strong><\/p>

(a) Movement of the earth around the sun: Periodic motion<\/u>.<\/p>

(b) Movement of ceiling fan: Circular motion<\/u>.<\/p>

(c) A rocket launched from the ground: Linear motion.<\/p>

(d) A fish swimming in water: Random motion.<\/p>

(e) The plucked string of a sitar: Oscillatory motion.<\/p>

Q.2. Fill in the blanks.
(linear, non-linear, uniform linear, non-uniform linear, uniform circular, random, circular, non-uniform circular)<\/strong><\/p>

(a) If a ball is released from the terrace of a building, it comes down in uniform linear<\/u> motion. On the other hand, it reaches the ground in non-uniform linear <\/u>motion if it is thrown with a force away from the terrace in a direction parallel to the terrace.<\/p>

(b) The motion of an aeroplane on the runway before take off is linear<\/u> .<\/p>

(c) The kite looking for its prey flies with circular<\/u> motion in the sky.<\/p>

(d) Children sitting in a rotating giant wheel have uniform circular <\/u>motion, while those sitting in a merry-go-round have a non-uniform circular<\/u> motion.<\/p>

(Linear, non-linear, uniform linear, non-uniform linear, uniform circular, random, circular, non-uniform circular)<\/p>

Q.3. How are we different?.<\/strong><\/p>

(a) Oscillatory motion and Linear motion.<\/strong><\/p>

Ans:<\/strong>\u00a0In oscillatory motion, body swings back and forth like Motion of a swing or motion of pendulum of a clock but in linear motion, an object shows displacement in a straight line like a train in motion or motion of soldiers on a parade.<\/p>

(b) Linear motion and Random motion.<\/strong><\/p>

Ans: <\/strong>Motion in a straight line is called linear motion and the motion that changes its direction and speed continuously is called random motion.<\/p>

(c) Random motion and Oscillatory motion<\/strong><\/p>

Ans: <\/strong>The motion that changes its direction and speed continuously is called random motion and the motion of a body that is swinging back and forth is called oscillatory motion.<\/p>

Q.4. Explain in your own words, giving one example each.<\/strong><\/p>

(a) Linear motion<\/strong>
Ans:<\/strong> An object that shows displacement along a straight line is called linear motion.<\/p>

(b) Oscillatory motion<\/strong>
Ans:<\/strong> The motion of a body swinging back and forth like a pendulum of a clock is called oscillatory motion.<\/p>

(c) Circular motion<\/strong>
Ans: <\/strong>The motion of an object along a circular path like a ceiling fan is called circular motion.<\/p>

(d) Random motion<\/strong>
Ans:<\/strong> The motion that changes its direction and speed continuously is called random motion.<\/p>

(e) Periodic motion<\/strong>
Ans:<\/strong> The motion of an object which passes through a certain point again and again after a fixed period is called as periodic motion.<\/p>

Q.5. Answer the following questions in your own words.\u00a0<\/p>

(a) Which types of motion are seen in birds flying in the sky?
Ans: The birds flying in the sky exhibit random motion and their wings show oscillatory motion.<\/p>

(b) Write in detail about your experience of various types of motion while riding a\u00a0bicycle\u00a0on a road.
Ans:<\/p>

  1. The\u00a0bicycle\u00a0itself shows linear motion.<\/li>
  2. The wheels of the\u00a0bicycle\u00a0show circular motion.<\/li>
  3. The bicycle chain shows periodic motion, if the speed is uniform.<\/li>
  4. The handle bar shows random motion.<\/li><\/ol>

    \u00a0<\/p>

    Q.6. Complete the puzzle using words for types of motion:<\/strong><\/p>

    (1) A spring is stretched and one end is released.<\/strong><\/p>

    Ans:<\/strong> Oscillatory<\/p>


    (2) A minute hand.<\/strong><\/p>

    Ans:<\/strong> Circular<\/p>


    (3) A see-saw.<\/strong><\/p>

    Ans:<\/strong> Periodic<\/p>


    (4)\u00a0 Children in a march past.<\/strong><\/p>

    Ans:<\/strong> Linear<\/p>


    (6) A stone rolling down a hillside.<\/strong><\/p>
