Question

1) Define angular displacement and angular velocity. 2) what are the uses of dimensional analysis?​

Answer 1

Explanation:

1)Angular displacement : The angle described by the particle about the axis of rotation in a given time is called angular displacement. Angular velocity : The rate of change of angular displacement is called angular velocity .

2)Dimensional analysis is used to convert the value of a physical quantity from one system of units to another system of units. Dimensional analysis is used to represent the nature of physical quantity. The expressions of dimensions can be manipulated as algebraic quantities.
