Wht dimensional analysis
Representation of physical quantities
Wht is fundamental quantities
Basic quantities upon which other quantities are derived
What are the important quantities in physics
Mass,lenght,time
What re the two things needed to specify a physical quantities
Number of quantities
Unit if measurements
Wht derived quantities
Derived quantities are those obtained from simple combination of fundamental quantities
Find the dimension of 2π√L/G
Answer is 2πT
Wht is motion
Change in position with respect to time
Wht kinematics
Study of motion of a body without involving the force which cause the motion
Classification of motion with defination
Random
Translational motion
Rotational motion
Periodic/oscillatory/vibratory motion
Wht is newton first law of motion
A body will countinue to be in a state of rest or uniform speed in a straight line unless acted upon by an external force
Wht is newton second law of motion
The arts if change in momentum is directly proportional to the applied fore an takes place in the direction of that force
Wht is Newton third law of motion
For every action there is an equal and opposite directo
Show the derivation of 2 law if motion mathematically
left for you to answer😏😌
Importance of dimension
To verify the correctness of a physical quantity
To derive the unit of a physical quantity
To drive the exact form of relationship between measured physical quantities
Wht is kinematic
Is the study of motion of a body without involving the force which causes the motion
Wht is inertia
Tendency of abody to remain in it state o rest or uniform motion
