(1) Heat lost through sides and /or Bottom False origin should be used if the values start far away from the origin. Cambridge International aS & a level Physics 9702 For examination in June and November 2019, 2020 and 2021. Find error by subtracting the gradient of best-fit from worst-fit. Take the following example: We add the fraction uncertainties of the involved quantities. (1) Use a remote-controlled clamp to release the object/ slot in tube + card/electromagnet due to a force which always opposes motion. Then it says to repeat the procedure and get six different sets of data in a table. ruler moves suddenly/without warning (so difficult to read newton-meter at the instant the ruler starts to move)/force drops to zero immediately after detachment Paper 5 is a written paper to test the practical skills that you acquired during your Cambridge International A Level course. (5) Reason for difficulty in measuring d e.g. travelling microscope Most people dont get the idea of best-fit line. Topic 13 Gravitational Fields. (2) Method to make uniform spheres/discs e.g. While measuring you should ensure that youpresent the data to the appropriate number of significant figures so that if reflects the least count of thedevice being used for example: And, yes,represent your alldata in the SI units..meter (m) for length, radius e.t.c. All points must be within2 cm (to scale) in x direction of a straight line. Very well explained, thanks. ** Below is the animation, showing:How to use Vernier Calipers? There must be an even distribution of points either side of the line along the full length, as we cancall the best fit line Insaaf Wali Line in Urdu, which means line doing fair treatment to all the points. Mention how you are going to make sure it does not change, and why you think it should be kept constant. (1) Method to reduce heat loss/lag/insulate/polystyrene container Using the same paper for explanations:(May/June 2018 Paper 5 Variant 2). How do we find uncertainty though, with the difference formula given in ms (eg s19 qp52 Q2). If the value of the quantity measured is very small, can write increase the magnitude of the quantity of the independent variable. Take the following example: When powers are involved in the given expressions, we find the uncertainties in the same way as above, with just a small change: we multiply the power with the fractional uncertainty of the value which is raised to that power. (1)Protractor wobbles when being held by hands/ Difficulty in measuring owing to container not perfectly right angled (curved) at the bottom/difficult to line up protractor/horizontal line of protractor not on table Once you are done algebraically manipulation the equation into a linear form, describe what the graph will look like if the given relationship is true, e.g. Along with all this, you are also required to mention the SETUP (discussed below) for the experiment; for instance, how you are going to place the LEDs/lasers (any appropriate method to support the light source, like clamping the light source using a retort stand, etc. The questions are arranged in topical form so that the students can revise and practice systematically.

By best-fit we mean average of allpoints line. Portuguese - Language 8684 Past Papers. Quickshop. ), fractional uncertainty in a =a/a = 0.2/2 = 0.1, fractional uncertainty in b =b/b = 0.3/3 = 0.1, fractional uncertainty in c = (a/a +b/b) = 0.1 + 0.1 = 0.2, absolute uncertainty in c = (a/a +b/b) * c = (0.1 + 0.1) * 1.5 = 0.3, percentage uncertainty in c =(a/a +b/b) * 100 = 0.2 * 100 = 20%. (6) String too wide for markings on rule . I dont mean that dont do the practicalaccurately but I mean to say that dont waste extra time in making it more accurate and leaving notime to complete rest of the paper. Rejected: (3) Difficult to judge end point Work fast and accurate. May I know whether I have to write gradient with unit? May 2022 papers for most subjects are available now! (5) Use of fiducial marker/pointer, Rejected:Do the experiment in a vacuum, switch the fans off, not just use video, light gates, Camera, High speed camera, Too fast, Time too fast, Time more swings , Time large no. Label the points with their coordinates.

Guys You save lives thank you for the post Just wrote maths p3 today and i knew everything but could not do everything because i was slow. It goes from 414.2 kilometers per hour (kph) to 0 kph in 2.8 seconds. (1) Ruler not vertical Join the three points together to form the error bar. Each question should take one hour asboth questions are of 20 marks. Watch on. then a calculation follows which requires you to substitute the values obtained inprevious calculation of gradient and intercept. First you will need to revise the equation of linear lines if you dont remember them. However, you will be given an error carried forward (ECF) for subsequent parts, and NO marks will be deducted as long as you calculated the gradients and y-intercepts correctly according to the graph you plotted.

I also stated all the instruments used too. Muhammad Ahsan. This critical thinking is very important to do the last part of this question, but the observations are made while doing experiment and setting up the apparatus. for d that you give MUST be equal to 2 s.f or 1 more (i.e. After measurements follow the calculations for finding out the uncertainty in the readings or calculating another value using a given formula by putting in the measure values. If you have done a good amount of practical work during your A Levels, this question wont be much of a concern for you (especially if you paid good attention to your paper 3 of Physics). Improvement: (2) Put coloured paper behind (object) /Description of method of reducing parallax error requiring additional equipment, e.g. We really hope it proves useful.
