Hi TiredMummy,

My DS is also weak in his Physics and I'm looking for a tutor for him too. Did you managed to find a suitable tutor? Do you mind sharing your findings? Thanks.

Hi, no, I couldn't find any one-to-one tutor and I saw a newspaper article abt Physics tuition at Bt Timah Shopping Ctr - Best Physics Tuition. I signed DD up and she is now into her 2nd mth. Too early to say if the tuition ctr is good or not.

Rgds,
Tiredmummy.

Hi parents, I wrote an article that will be helpful for students taking physics at O or A Levels!

4 Must Try Tricks If Your Child Is Struggling With Physics

Tip number one: Focus on understanding each topic separately

Tip number two: Prioritize understanding over memorization

Tip number three: Do as many practice synoptic questions as possible

Tip number four: Keep a log of all the difficult question types

Also, help your child during exams with these FREE E-Books! (Leave your email and we'll email you a copy!)

Thanks


Yes answer is A.

A convex mirror is used in seven-eleven to enable wide range of vision. The objects will look smaller. See it for your sell at any seven eleven store :)

These are the kinds of questions we go over with students during our September Holiday Program for End of Year Exam Revision (including IP) and O'Level Physics. I'm doing a lot of these problems with Sec 3 and Sec 4 students as well in our regular Physics tuition classes.

The answer is in two parts. For the first part, use a kinematics equation to solve for the initial velocity. We strongly recommend memorizing the 4 equations used for kinematics, as this is the fastest way of solving these kinds of problems.

For the second part, set the calculated kinetic energy = 95% of the actual kinetic energy. This needs to be done carefully. This little step at the end comes up in a lot of places in physics where efficiency is involved and it is important to think about the answer at the end. The actual initial velocity must be higher than the calculated initial velocity because energy was lost along the way.

Hi all
May I know what could be possibly tested under “Waves” for SPA? :scratchhead:
What should the child take note and prepare for this topic?
I would appreciate suggestion.
Thank you very much.

Hi,

Are you referring to the topic General Wave Properties as opposed to Light/Electromagnetic Waves? I don't teach Physics and it has been a couple of years since I did Physics SPA but I'll try to recall what I've done. :)
