I recommend you study Paul Vunak's training techniques. The video in the links below covers all the essentials to establish a good foundation for effective self-defence as well as offensive attack, spanning a broad range of martial arts techniques.
The video starts with effective footwork and continues onto the full range of effective punches, which are extended into the use of elbows, kicks, knees and head-buts.
Use of the heavy bag is shown towards the end of the video.
The whole video is worth watching (and using as a guide to regular training), but, in order for you to quickly assess it's suitability as a training aid,
..... I have preset the first link to start at the introduction to effective punching; and the second link to the start of "equipment training" covering the use of protective hand wraps and heavy bag training.
I hope you find it useful.
Most people do not know how to throw a punch properly but here is a start, looking at the fist.

there are many ways to get force but you will have to find the right teacher for that
just pound it.
Swing your arms like a pinwheel and shout "Flurry of Fists of Fury!" as you rev up your swinging. Then just walk into the bag and let your fists do the talking.
Go to a boxing gym or something
Your entire body should be used into throwing that punch, your power and bodyweight should be behind it.
I have a bag but i dont know how to punch it? How to punch? do i have to slide my shoulders?
