Role of actin + myosin

What are roles of actin + myosin in context of muscle cells

I tried searching up for ages to find a good answer but I can't find any

Someone help me out please
Look into the sliding filament model. If you look up the spec for your exam board (eg. ocr, aqa,edexcel etc) you'll find exactly what you need to know. I also recommend getting a textbook for A-level biology as it will answer most of your questions and you won't need to wait for a response from tsr.

I put these:
Actin: spherical protein that forms filaments + involved in muscle contraction + other important cellular processes

Myosin: protein that converts chemical energy in form of ATP to mechanical energy

I tried using the edexcel textbook but it doesnt explain the roles of these proteins
they attach to eachother + stretch in order to make muscles move. I don't know how in-depth of an answer you are looking for
