    Do you have any worksheet/lesson regarding Momentum & Impulse as we have started this in class.

  2. Blue.blood says:

    This is an awesome website helped me to a great extent ,
    Keep up the good work Mr.Patterson

  3. rushi says:

    Sir can you make any powerpoint showing how genetic disorder works in Meiosis process

  4. rushi says:

    Mr. patterson can you please upload the exam question paper i want to do the ticker timer which was asked in Science exam

    • Mr. P says:

      Sorry, I am not allowed to give out the exam papers or the solutions. There are similar questions on a worksheet found under the Physics section of “Year 10 Worksheets”

  5. Marcus Koh says:

    would newton’s 3rd law be on the exam?

  6. Leroy says:

    I’ve been doing your Chemistry “Final Test Revision” papers, and I must say I’ve gotten a little rusty on the “mole -> molar mass -> mass” bit of Year 10 chem… Thanks for the prac papers, and helping me realize that I’ve got some problems which need fixing o.O Would you be so kind as to help me with question 2 of the Final Test Revision 2, for example? Kinda worried about this :/ Thanks

  7. Vidit Vashisht says:

    What are the reactions we need to know for the exam?

  8. Amir Khodadad says:

    can you please upload the soloutions for the year 10 exam revisions (1 & 2)

  9. Joshua kim says:

    for the chem section of the exam. Do we get a periodic table and a solubility table?

  10. Joshua kim says:

    For question 2. 1st and 3rd from the Semester 1 Exam Revision. Are they asking for a moth or a human?

  11. Joshua kim says:

    what are going to be the main topics in all the areas of the exam next week?

    • Mr. P says:

      Biology, chemistry and physics.

      We have done less than four weeks on each topic. Anything could be put in (except gravity problems in physics)

  12. Melvyn Hiong says:

    do we need 2 kno how 2 add vectors in 2 directions

  13. Melvyn Hiong says:

    but u said the yr 10 teachers decided 2 remove acceleration from the exam

    • Mr. P says:

      I said acceleration due to gravity is not in it.

      That means no problems involving falling objects. Objects like cars and trains which accelerate horizontally will be included.

  14. Melvyn Hiong says:

    will be in the exam

  15. Melvyn Hiong says:

    but s=ut+1/2at^2

  16. Melvyn Hiong says:

    and it will not be in the exam

  17. Melvyn Hiong says:

    so we dont need 2 know anything 2 do with a=v-u/t

  18. Joshua kim says:

    ok, thanks.

  19. Zul says:

    What does it mean when it says “5th second of travel” in set 11: question 7?

  20. Joshua kim says:

    With vectors do we have to use the harpoon arrow thing? or is it ok if we don’t use it?
    Also when an object uses ‘uniform retardation’, does that mean it is decelerating?
    And in the exam/test, will there be gravitational acceleration? and if there is could we round it up to 10 instead of 9.8 to make it easier?

    • Mr. P says:

      While there will be no marks removed for missing the harpoon arrow it is good practice to be using it, particularly if you are heading towards Physics in year 11.

      Uniform retardation is the same as uniform deceleration, yes.

      The year 10 teachers have decided to remove acceleration due to gravity out of the test. However, you will still need to be able to use the formula s= ut+ 1/2at^2

  21. Melvyn Hiong says:

    How long will we get 4 the exam

  22. Melvyn Hiong says:

    In physics what is the formula for time

    • Mr. P says:

      We have several formulas with time in it.

      v=s/t
      v= u + at
      s = ut + 1/2at^2 (^2 means squared)

      If you need to find time you must rearrange one of these formulas using algebra techniques.

  23. Gabbie Lillo says:

    When’s the exam again?

  24. Melvyn Hiong says:

    can u please solve set 7 Q1(b) and (c) from matthews and winters book

    • Mr. P says:

      Do not concern yourself with set 7 as it is more advanced than is required. Did I say to do it? I realised later that all the problems were actually in 2 dimensions when we only care about 1 dimension in year 10.

      7c is zero because if the athlete completes a lap his displacement is 0 (back at the start). velocity = displacement/time =0/440 = 0.

  25. Melvyn Hiong says:

    When writing a reaction will metal hydroxide always be (s)

    • Mr. P says:

      Most of the time yes. Think of adding a powder (metal hydroxide) into a beaker of acid. The metal hydroxide starts as a solid.

  26. Melvyn Hiong says:

    for the exam will we need to know the states of matter
    eg. (s) (aq) (l) (g)

  27. Melvyn Hiong says:

    For the year 10 science exam revision semester 1 i dont get how to solve Q8
    Tony has attached ear lobes. What is his mother’s genotype?
    and Lisa has attached ear lobes. What gene did she get from her father?
