Through this two sets of practice paper, i had learnt new things which i have a misconception in the past. After doing and marking the two sets of paper, i am able to know where is my strength and weakness. I time myself with 1hour 30minutes to test how fast can i complete the test papers. Incredible, i am able to complete it within 1hour 15minutes. With the remaining 15minutes, i use it to check my practice paper before marking it myself. After marking it and doing corrections, i can focus more on the ones that I answered it wrongly, so that i can memorize it and do it correctly next time. 1. how are we able to calculate the force when the swing is swinging
2. does height of the pendulum affect the force that is travelled side to side 3. how are we supposed to calculate the time of the force 1) Make sure that whatever you are measuring is clean and has no burrs on the edges. 2) Open the jaws of the caliper and position them on both sides of the piece you are measuring. 3) Push the jaws firmly against the workpiece. 4) Lock the clamp screw so that the jaws don't move. 5) On the vernier scale is a small number 0. Look at how many inch divisions it is past on the bar scale. 6) See how many smaller (numbered) divisions the small 0 has gone past. This represents how many tenths of an inch the workpiece is measuring in addition to the number of whole inches. 7) How many smaller divisions has the small 0 gone past the last numbered division, this number multiplied by 25 is how many hundredths of an inch. 8) Determine which division line on the vernier scale best lines up with a division on the bar scale.This is how many thousandths of an inch. 9) By adding the inch measurement, the tenths of an inch, the hundredths, and the thousandths, you will have a measurement to a 3 decimal place accuracy. |
