Centre Of Gravity Flashcards
What is meat by the term centre of gravity
It is an area of an object which all weights appear to act on
How to find the centre of gravity of an rectangular shape
Draw a line from top right to bottom left corner
Repeat on other sides
Where two lines meet in the centre of gravity
What is the equilibrium
An object that is balanced
Name the two types of equilibrium
Unstable equilibrium
stable equilibrium
What is a unstable equilibrium
A object that will not return to the same position if it is slightly moved
What is a stable equilibrium
A object that will return to its position if moved
What is the importance of stability
If an object isn’t stable it may topple over
What will happen if a object isn’t stable
If the weight acting on the centre of gravity of an object passes the outside base it will topple over
How can you improve the stability of an object
Have a wider base for the object
Make the centre of gravity lower on the object
