First Month in Physics

For me Physics is a hard but a cool subject, it has many complicated problems but as you go over, it becomes easier because you encounter many experiences already. This month looks like a trouble but when it goes on, it will be simpler. The hardest lesson in this month is the SOHCAHTOA.

Finding Vector Using Component and Graphical method.

Graphical Method

-In this kind of method, we use graphics in finding the vector. These are the procedures in finding the vector:
1. Draw side AB with the given length. Then draw side AC.
2. Given side AB and side AC with the given length, connect point B to point C.
3. Measure the length of AC.

Component Method

-In this kind of method we use the components of x and y to determine the vector. These are the procedures in finding the vector using component method:
1. Given the vector that the endpoint is on the origin (for example side AB), and its position, make a right triangle by tracing broken line which will form point x(on the x axis) and y(on the y axis) and side AX and AY which will be the base and height of the triangle.
2. Given the distance of side AX and AY, then use the cosine(distance of x) and sine(distance of y).
3. Use the pythagorian theorem [AB(squared)= AX(squared) + AY(squared)] to get the vector AB.
