IGCSE Physics Length and Time Solved Past Paper MCQs

IGCSE Physics Length and Time Solved Past Paper MCQs.

In this video I will take you through a few questions which appear to be very simple but many students make silly mistakes while solving them.

Some of the topics discussed in the video are:

1. Mistakes made while taking readings from measuring cylinder .

2. Next we have relationship between length and width of the measuring cylinder to the accuracy of the readings taken. This concept can come very handy in understanding and solving questions related to length and diameter of thermometer tube.

3.Many questions involve measuring length when ruler is not placed from the starting point, these questions some time have many sub parts, so if in first step reading calculated is wrong all parts are done incorrectly . So although it is simple but is quite critical.

4. The Rolling cylinder problems are quite common. these problems either ask you the circumference, the diameter or the radius of the cylinder rolling on a flat surface. This concept is discussed in addition to forewarning students of irrelevant information in the question provided at times to confuse them.
So stay focussed to the problem and information required.

5. Most of the time related problems have one common factor in them, that is the time provided is in different units. After converting them to the same unit, most of these problems can be solved easily using simple addition and subtraction.

6. Finally, a rather interesting problem of measuring volume with a ruler is also explored .

So go ahead, watch the video till the end and enjoy Physics...
