PHYSICS!!

[Keitak]

What are the types of questions that would appear in physics paper 6?

 

[Zohaib Sherazi]

The atp ? Its paper 4. Experimental design qsts. Drawing results from experiments, plotting graphs, making further deductions from the results, accurate use of measurement instruments, avoiding errors, suggesting improvements.

thanx!

@zohaib : can u giv some general answers to:
Experimental design qsts. Drawing results from experiments, plotting graphs, making further deductions from the results, accurate use of measurement instruments, avoiding errors, suggesting improvements.
PLZZZZZZZZZZZZZZZZZ

 

[Zohaib Sherazi]

You can ask about specific qsts.

 

[Talha]

Plz answer the following:
(1) how to increase our measurement accuracy nd how to avoid errors while using metre rule, vernier callipers, micrometer screw gauge, pendulum, stopwatch nd thermometer.

(2) suggesting improvements for circuits,pendulum, moments ques,transfer of heat energy, lens nd light ques.

 

[Zohaib Sherazi]

Accuracy depends on the instrument being used. So, the diameter of a ball bearing an be more accurately measure by using a micrometer screw gauge than a vernier caliper. Error can be avoided by placing the eye perpendicular to the scale when taking readings and checking for zero errors before taking a reading. In case of thermometer by using a thermometer with smaller divisions.

Improvements can be done by improving the accuracy as suggested above and repeating the readings and taking the mean.
