Center of Gravity:
The center of gravity is the average location of the weight of an object. Completely describe the motion of any object through space in terms of the translation of the center of gravity of the object from one place to another, and the rotation of the object about its center of gravity if it is free to rotate.To know more about Center of Gravity,watch Center of Gravity Video to learn more .
A lower center of gravity. The center of gravity (CG) of an object is the point at which weight is evenly dispersed and all sides are in balance. A human’s center of gravity can change as he takes on different positions, but in many other objects, it’s a fixed location.
Follow me through a quick experiment:
- A #2 pencil
- A fine edge like a ruler or a credit card
- A permanent marker
- A ruler (if you don’t have one, you may be able to eyeball it)
Step 1: Attempt to balance the pencil on the edge you have selected. Balancing the pencil may take some trial and error. The point at which the pencil balances may not be where you first thought. If it begins to tip in one direction, move the pencil back slowly in the opposite direction until it will stay there on its own.
Step 2: Once the pencil is balanced, mark the location of the balancing point with a permanent marker.
Step 3: Measure the distance between the ends of the pencil and the balancing point you have marked. Are the two lengths equal? On my pencil, the length from the eraser to the balancing point was actually 1.25 inches less than the length from the pencil tip to the balancing point.
Keeping Up with the Center of Gravity
The center of gravity is an important concept in determining the stability of a structure. It’s the reason why a good homeowner will keep the top branches of his trees trimmed. It’s also the reason why a pick-up truck might not be the best vehicle choice for a first time driver.
