reminders

Question 1

Learn

Answer 1

Formulas not in log table that are needed

Question 2

When defining

Answer 2

-when you add a formula to the definition, make sure to write a key on what the letters/symbols stand for!!

Question 3

when calculating during experiment questions

Answer 3

find the average value!!

Question 4

heat questions (Experiments)

Answer 4

do not include calorimeter in calculations if “styrofoam” or perfect insulator

Question 5

when you say “use insulation” as an answer

Answer 5

write examples

Question 6

“using the graph…” during experiments

Answer 6

use the graph for calculations, dont use the values in the value table!!!

Question 7

graph question

Answer 7

• dont forget to add title at the top
• write titles of x and y axis and their measurements
• configure the values before plotting them if needed
• draw a line through the values
• plot accurately, make sure the plotted points are clearly visible

Question 8

when doing calculations

Answer 8

ALWAYS PUT EVERYTHING INTO SI UNITS AND PUT THE MEASUREMENT IN THE END!!! (EG. M/S)

Question 9

when doing qs

Answer 9

-read the questions CAREFULLY!! do not miss a question that was written within another question

for example, “Draw a suitable graph to show the relationship… State this relationship and explain how your graph verifies it”
-DONT FORGET to do the last 2 questions after doing the graph!!

Question 10

period

Answer 10

The period is the time it takes to complete one full cycle. The period of a pendulum is the time it takes for the pendulum to swing from left to right and back again.

Question 11

angle

Answer 11

when using angles, use rads!!!!! the angular displacement is in rads, the angular velocity is in rad/sec

Question 12

units

Answer 12

use the values they give u at the bottom of the question eg. if they say use g = 9.8

Question 13

when writing definitions

Answer 13

give examples whenever u can

Question 14

charge, current, time formula

Answer 14

Q = It

Question 15

diagrams

Answer 15

learn diagrams on the extra sheets

Question 16

Modern physics diagrams to learn

Answer 16

on ppt slide

Question 17

before doing calculations

Answer 17

check at the bottom of the qs if they give you any constants that are rounded up!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Question 18

units

Answer 18

make sure to give answer in units they want if there is a stated unit, eg “ in years” –> turn seconds to years!!

Question 19

dont forget

Answer 19

• write the correct units
• give answer in units/decimal points that they want if they specify
• write out all calculations
• always write formulas down before starting calculations
• pay attention as you do calculations, don’t accidentally change values in the middle of them
• change everything to SI unit!!
• make sure you fully understand what they want and what to do before attempting the question

Question 20

when converting units

Answer 20

if unit is x/y, x and y are calculated differently!! remember the rule

Question 21

when doing graphs

Answer 21

make necessary conversions/adjustments to values before drawing graph (eg. sin i / sin r graph, not i vs r graph)
