Hi. I need help with a quick concept. So there is a string hanging vertically making the bottom of the spring its equilibrium point. A mass is added on it creating an amplitude. If I were to pull down on the mass and let it oscillate passing its original equilibrium point, does that mean a...

Thank you so much :))

Awesome, thanks! :)

Ohhhh I get it, so if I just put a pencil on the table and don't touch it, it still has gravitational potential energy right?

But I thought that it can only have gravitational potential energy if it has height..also I don't understand how it is able to start off that that much kinetic energy right from the beginning :(

Hello PF. I have a question on a concept of Potential and Kinetic energy. So for this let's take a ramp and a ball at the bottom. If I apply a force on the ball to make it go up the ramp, when it starts to move it will gain kinetic and potential gravitational ( I think ) but what about at the...

Oh ok got it thanks :)

Just a quick question,so the x-comp can always change? So it is not always cos or sin but it depends on where the center of motion is right?

sine!:)

Green comp

I think its to the left

Red line I believe

Green would be sin and red would be cos. so T cos(θ) = mv2/r T sin(θ) = mg

But even it was at a different spot, wouldn't the horizontal always be cos?

Got it ty so much for help :)
