00:00hello everyone welcome to my youtube channel today we will learn the relation

00:14between equations in linear motion and equations in rotational motion or

00:21angular motion is the distance formula is equal to s is equal to V into T so in

00:35rotational motion this equation will become is we will write theta in place

00:41of s is equal to and omega in place of V and time will remain same so this

00:52equation is used in linear motion and this equation is used in rotational

00:57motion the second one is the first equation of motion V is equal to U plus

01:09A into T so in rotational motion the first equation will become is omega f is

01:21equal to omega I plus alpha into T means time the next one is the second

01:34equation of motion s is equal to U into T plus 1 upon 2 A T square so in

01:46rotational motion this equation will become is theta is equal to omega I here

01:56U stands for initial velocity so here initial linear velocity so in rotational

02:04motion it will be initial angular velocity omega I into T plus 1 upon 2

02:14there is linear acceleration so in rotational motion it will be angular

02:19acceleration alpha so T square will remain same the the third one equation

02:29is V square is equal to U square plus 2 A s so the third equation in rotational

02:45motion will be is omega f square is equal to omega I square plus 2 into alpha

02:57into theta the equation for average velocity in linear motion will be V

03:09plus U upon 2 and in angular or rotational motion the equation for

03:18average velocity will be

03:23means average angular velocity is equal to final angular velocity plus initial

03:33angular velocity divided by 2 here omega f denotes to final angular velocity and

03:40omega I denotes to initial angular velocity here V is equal to Vf means

03:55final velocity and U is equal to Vi means initial velocity

04:13and here theta denotes to angular displacement and omega f is final

04:43angular velocity omega I is initial angular velocity and alpha is angular

05:14acceleration so dear students that was about the relation between linear and

05:22rotational equations
