Pseudo force Definition and 18 Threads

How is the equation for the force derived? ##\vec F_{rot}## should be sum of ##\vec F_{in} \pm \text{ pseudo force }## which is the centrifugal force. SO $$\vec F_{centri}=2m(\vec v_{rot}\times \vec \omega)+m(\vec \omega\times \vec r)\times \vec\omega$$ which does not seem incorrect Why is it...

$$ \frac{62 - .4mg + (.2) (m_{net} g)}{m} = a(t)$$ And, then I put ths into $$S=\frac{1}{2} at^2$$ But, my answer is not quite coming with what's in the options? So, my main confusions are, SHould the bottom most surface exert a force on the top most block, also where am I making mistakes...

I'm often got confused about why the direction of pseudo force is taken opposite to the direction of motion of the body. As specific, I have this question. In this, I didn't understood about why the direction of pseudo force is taken in right, in the diagram of solution provided to this...

I know that, if my ##X## axis is aligned with the arm, there is friction pointing to ##O## and the ##x## component of the weight. Then, on the ##Y## axis, there is the normal force and the ##y## component of the weight. Supposing that I am situated on the arm (non inertial frame), where is the...

At the moment of throwing the ball the ball will have a vertical vel of 4 and horizontal of 3 wrt to elevator so as seen from inside the elevator the ball will behave like a projectile where g(eff) = 8 and with time period 1 sec hence range will be the displacement which should be 3 m but ans...

Here is the problem in Morin. In this problem he takes the person on carousel as origin. Accordingly,when he begins to apply Newton's Law of motion on himself,by the equation of pseudo force,since he is motionless in his own frame,his own acceleration is 0. Further in his own frame he has 0...

Hello everyone. This is my first time on the physics forum, but I think I'm going to be a regular here. I was reading a paper that outlined various ways to approach solving dynamic problems. The first approach outlined by the author is D'Alembert's principle of virtual work. In describing...

Homework Statement The system shown is initially at rest when the bent bar starts to rotate about the vertical axis AB with constant angular acceleration a 0 = 3 rad/ s2 . The coefficient of static friction between the collar of mass m = 2 kg and the bent bar is f.Ls = 0.35, and the collar is...

Homework Statement A block floats partially submerged in a container of liquid. When the entire container is accelerated upward, which of the following happens? Assume that both the liquid and the block are incompressible. A) The block descends down lower into the liquid. B) The block does...

Homework Statement A homogeneous flexible rope rests on a wedge whose sides make angles α and β with horizontal. The centre of rope lies on C. With what acceleration should the wedge be moved for the rope to stay stationary with respect to wedge? (all surfaces are smooth). Homework Equations...

If you have a car and a pendulum is hanged inside it, and if you watch from outside the car,and if the car has some acceleration, then you see the bob moving in opposite direction of motion of car. For a person standing outside, he knows that the car has some acceleration. What causes the bob...

Q1) What angular velocity would be required for your effective weight at the equator to be third of that the north pole? You may neglect all inertial forces except the centrifugal. I understnad the majority of my books solution which is that: At the equator, the centrifugal force is...

Homework Statement a block of mass m is resting on a wedge of angle θ as shown in fig. the wedge is given an accn. a towards left.what is the minimum value of a due to an external agent for which the mass will fall freely? Homework Equations N+m(asinθ) = 0.(N is the normal force)...

Can anyone tell me books for reading about the pseudo force?

what is pseudo force and centrifugal force? can anyone differentiate between them? is one a special case of the other?

Homework Statement A block of mass 50g is suspended from the ceiling of an elevator.Find the tension in the string if the elevator goes up with an acceleration of 1.2m/s^2 Homework Equations F_{net}=ma_{net} The Attempt at a Solution I have reached here:...but with this i don't get the...

I was reading about the Principle Of Equivalence as proposed by Einstein which proved that Inertial Mass and Gravitational Mass is one and the same thing. Further it proved that if we are in a spaceship and flying in space with acceleration 'g' upwards, the person is bound to the surface of the...
