guys pls tell the meaning of rotation of bodies without sliding and without rolling??

Sai Sri Nandan Ch 13th Apr, 2020

Hello,

Physically, a body in rotational motion without either sliding or rolling, will rotate about a fixed axis. Example: a ceiling fan.

The basic difference among the three groups is:

In sliding, the particles of the object are in linear motion. While in rotational motion, the particles rotate around a

can we apply acceleration a=(gsintheta -Musgcosheta) in rolling motion in case of inclined plane and find out time taken by substuting value of a in kinematic equations??

Mounika Sonti 29th May, 2020

Hello!!!!

Hope you are doing great!!!

Yes , We can apply a=(gsinθ - μgcosθ)

Σ F = Fg - Fk  ( Fg is force exerted by the block , Fk is the frictional force,  we can consider frictional force according to the question)

Σ F=(mgsinθ - μmgcosθ),,θ is the angle

guys can we apply kinematic equations for rolling body in inclined plane??

Soutrik Acharya 18th Apr, 2020

Hello,

You can definitely apply kinematics equation for Rolling Body in incline plane full stop if you can apply the equations correctly then you can see the problem has reduced to a very simple equations and  it's easy to solve it it then the normal problems.

Thank you.

the angular velocity and amplitude of a simple pendulum is omega and A respectively at a displacement x if its KE is T and potential energy isU then the ratio of T to U is

KUNAL LANJEWAR 13th Apr, 2020

Hello,

We know that, for Simple Pendulum,

Kinetic Energy = T = [ m.ω^2 ( A^2 − x^2 ) ] / 2

Potential Energy = U = m.ω^2.x^2

Hence, Ratio of Kinetic Energy to the Potential Energy is,

T / U = ( A^2 - x^2 ) / x^2

i.e.,

Two particles p and q start from origin and execute simple harmonic motion along x axis with same amplitude but with period 3 seconds and and 6 seconds respectively the ratio of velocities of p and q when they meet is ......

KUNAL LANJEWAR 13th Apr, 2020

Hello,

We know that, for Simple Harmonic Motion,

Velocity at mean position =Vmax = A.ω, where, ω = 2π / T

So, p = A.2π / T1   ( Since, A1 = A2 = A )

and q = A.2π / T2

So, p / q = T2 /T1

So, p
