@Ranbir.Bhardwaj 2 жыл бұрын

At 2:22 you said that force exerted by the spring is always opposite the motion But while coming towards centre, force and motion are in same direction. Shouldn't it be like ' force is opposite to the direction in which spring is streched or compressed' ??

@carultch Жыл бұрын

I'm sure that's ultimately what he meant. The spring force is a restoring force, which is proportional to and opposite the deformation from its neutral unstressed position. The spring force doesn't "know" what the velocity or acceleration is of the mass. Viscous drag would be proportional and opposite the velocity, while the apparent "inertial force" (D'Alembert Force) of the mass is proportional to and opposite the acceleration.

All jokes aside Dave. I was a inspector for a railroad and there is something called a harmonic unbalance it say. The difference between cross level between rails in 7 consecutive joints can not exceed . If I remember correctly it is 1 and 5/8 of a inch and if it does the track must be slowed to 10 mph. . Rail length are about 32 feet so a joint are staggered every 16 feet . If not a train car will rock off a track. I assume it is similar to a tsunami in the ocean.. why would that cause a harmonic unbalance.?

@sepm7356 6 жыл бұрын

would Fspring always be negative value since by def its Fspring = -kx?. cause on the comprehension, when the spring is stretched, Fspring and spring constant were both negative resulting in positive distance which makes sense since the distance is getting stretched making the distance longer to the right from the equilibrium position. But if we changed it to the spring being compressed. We can make Fspring positive value right? since +Fspring / -k will result into -x(distance) which makes sense also since the spring is being compressed down making the spring shorter away from the equilibrium to the left?

@RicardoSanchez-fp9kz 6 жыл бұрын

no, fspring can be positive or negative. lets say the spring is in equilibrium and you define stretching to be positive. when you stretch it 1m then multiply by -k you will get a negative force. thats because even tho youre pulling it with a positive force that equation gives the force the spring is applying to your hand. so youre pulling at +15N (to the right) the force the spring is applying is negative (to the left) because its try to get that block back to equilibrium. Now lets say you compress with a force -15N (to the left) that equation will give you a positive spring force (to the right) because it wants to get that block back into equilibrium.

@RicardoSanchez-fp9kz 6 жыл бұрын

or a TLDR: define one direction as positive and the other as negative and just plug in the direction. so -k * -x give positive force and -k * x gives negative force. ty very much

@mahboobraju 3 жыл бұрын

Look the equation F=-kx will automatically give the direction of the force for eg. When the particle is somewhere between mean position and positive extreme then x will be positive and hence the force will act towards the negative x axis.....as the acc is towards the -ve x axis and vice versa

@carultch 2 жыл бұрын

It is negative because it is a restoring force that returns the spring back to its unstressed position. Force is opposite the displacement from the rest position of the spring. It isn't always linear with the displacement, because eventually if you stretch a spring far enough, you'll take it past the point of no return, where it will permanently deform. Force vs distance is not a linear function once you cause the metal to permanently deform.

@shivkumarverma9124 2 жыл бұрын

It's acting opposite to the direction of the force we apply, suppose a mass is connected to a spring. We apply the force on the right side, the spring tries to pull us backwards to get back to its natural length. That is, to restore equilibrium. So the force is negitive.

@richardlu0928 5 жыл бұрын

I'm also a physics student now so I'm not sure my answer is right or not. I think F=kx is for the force required to stretch the spring, and 1/2kx^2 is for the elastic potential energy which is Ee, one is energy and another is force. Hope this helps!

@carultch 2 жыл бұрын

@@richardlu0928 Your answer is entirely correct. And you will find that if you take the negative integral of -k*x, you will get 1/2*x^2. Potential energy is the negative integral of force relative to position, when the force is conservative. More generally for the 3-D case, force is the negative gradient of potential energy.
