By studying this chapter students will be able to: Define momentum, force, inertia, friction and centripetal force. Solve problems using the equation Force = change in momentum / change in time. Explain the concept of force by practical examples of daily life. State Newton’s laws of motion. Distinguish between mass and weight and solve problems using F= ma, and w = mg. Calculate tension and acceleration in a string during motion of bodies connected by the string and passing over frictionless pulley using second law of motion. State the law of conversation of momentum. Use the principle of conservation of momentum in the collision of two objects. Determine the velocity after collision of two objects using the law of conversation of momentum. Explain the effect of friction on the motion of a vehicle in the context of tyre surface, road conditions including skidding, braking force. Demonstrate that rolling friction is much lesser than sliding friction. List various methods to reduce friction. Explain that motion in a curved path is due to a perpendicular force on a body that changes direction of motion but not speed. Calculate centripetal force on a body moving in a circle. State what will happen to you while you are sitting inside a bus when the bus

  1. Starts moving suddenly
  2. Stops moving suddenly
  3. Turns a corner to the left suddenly

Write a story about what may happen to you when you dream that all frictions suddenly disappeared. Why did your dream turn into a nightmare?

Correction and Comments about Numericals and Short Question Answers

  • Numerical 2.9
    Question Asked by Maria Khan : The answer of numerical 2.9 of 2nd part where the distance is asked to find is, not coming correct.so please check this.your answer is 266.53m but through calculator is 296.14m.plz solve this query.
    Answer : Actually, the value of 266m comes when you do not round off the value of acceleration (means a= -0.3331666875 m/s*s) and all other velocities. So your answer is also correct because you round off the value of acceleration. In exams I would say that write the value of distance 296m because this is the value you computed after rounding off and it is correct also.
  • Numerical 2.8
    Problem : Incomplete Numerical and missing page number 14.
    Remaining Part:
    0 = 6vi – 180
    vi = 30m/s
    Now calculating height reached by the ball
    using formula 2as = vf2 – vi2
    putting values in the above formula
    s = (vf2 – vi2)/2a
    s = (0 – 30*30)/2*9.8
    s = 45m approx
    Hence the height reached by the ball is 45 meters and the initial velocity is 30 m/s

    Problem: Wrong answer given in notes.
    Correct Answer:  It is the measurement or value that an instrument shows when it should be showing zero.
  • Short Question 1.9
    Problem: Wrong answer given in notes.
    Correct Answer: By knowing the zero error, necessary correction can be made to find correct measurement. Otherwise our reading will be incorrect.
  • Numerical 1.7
    Problem : Wrong values of pitch of the screw guage(0.1mm) and number of division(100).
    Correction:  The vale of pitch of the screw should be 0.5mm and number of divisions should be 50 according to the question. There is no change in answer, it remains the same.
