Title: BALANCE BODY RIGID
I. Purpose
- Determine the location of the center point of equilibrium (measuring)
- Comparing the center point of measuring results with theoretical results
II. Basic theory
CENTER OF MASS AND THE WEIGHT
The center of mass and center of gravity of an object with the same meaning, which is a point where the mass berpusatnya / Be
III. Tools and materials
- A piece of cardboard rectangle, sides length ± 25 cm, which will look for the center point of equilibrium
- Pencil / pen / other objects pointed sharp enough to be used to perforate the field of cardboard
- Yarn, which is necessary to hang the cardboard as well as being auxiliary to signify the direction of gravity carton
- A ballast that can be hung by a thread, to keep the thread directions of gravity remains tense (not loose)
- Scissors / cutter, used to form a field of 2-dimensional cardboard
IV. activity
A. Implementation
1. When the two-dimensional field of cardboard in the form of any quadrilateral, cardboard made into a square / rectangle to set the length and direction of the sides using scissors / cutter. Measure and record the length and width of the rectangle.
2. perforate the field carton with 4 holes are located a maximum amount of smoking that can be entered thread.
