@drgermankills7963 3 года назад

The negative sign in the equation is simply indicating that the force is opposite of the direction of the spring displacement.

@Ranbir.Bhardwaj 2 года назад

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 2 года назад

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.

@jhelseaamarixe4475 4 года назад

4:10 is the force always negative like the constant? or if we only pull it then that's when it's negative?

@blinkbubs3994 4 года назад

always negative

@mahboobraju 4 года назад

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 3 года назад

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.

@shanestewart1252 2 года назад

Thanks Dave. Your video reminds me of Baywatch. There is a lot of harmonic motion seen when people run on the beach.

@shanestewart1252 2 года назад

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.?

@bensonchipoka5443 Год назад

@BirnieMac1 3 месяца назад

Okay but what if they’re not letting us simplify it without friction anymore Is it just setting up the equations of motion and taking the sum of forces (friction opposing motion)?

@anirudhsarang2480 4 года назад

Thanks a lot feel benifitted

@eriksambong8806 3 года назад

I would like to ask why the force has a negative sign. Is it because it is stretched?

@shivkumarverma9124 2 года назад

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.

In which scenario do you know to use 1/2 kx^2 instead of -kx

@richardlu0928 5 лет назад

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 года назад

@@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.

Will the springs energy not eventually stop the Block 😂 stop moving thus it finally ultimately becoming a single motion just like the rock dropping? Genuine question as a learner.😅

Even the pendulum eventually the clock will need winding again thus ultimately becoming a single motion of the spring expanding its energy? 😅🫣
