WebThe Centre of gravity is a theoretical point in the body where the body’s total weight is thought to be concentrated. It is important to know the centre of gravity because it predicts the behaviour of a moving body when acted on by gravity. It is also useful in designing static structures such as buildings and bridges. WebSep 19, 2024 · PPT. PDF. PDF. Class 8 – videos, ppts, worksheets, solutions and notes.
