Can't give parts a velocity/they wont move

[magic turtle]

So i just started scripting and i figured out how to create parts, give postions, colours, sizes and whatnot. Then i tried to create moving parts but it's not working no matter what i do. I've searched this up but a lot of the results were unrelated and the only result i found relied on constantly increasing the position by 1 in a loop which isn't what im looking for.
There's no error message in the output either.

I'm trying to give the part a velocity of 15 in the x axis but whenever i run it the part is stationary. I tried making it massless, changing the size, tried increasing the max force but i can't get it to work.

Am i using the wrong property or something?

?

using math.sin

using tweenservice

using loop

you shouldnt use math.sin and loop

i suggest u to use tweenservice

its better

[magic turtle]

how do i go about using tweenservice?

i've never used it and dunno how to

(nor what it does actually)

[dull mural]

you should learn about it or watch a vid about it, It's not hard

[magic turtle]

got it, ty

it basically change a part property until it's reached the goal property
