It is most likely an extension or plug-in, possibly incompatible with Yosemite.

Try going to Safari > Preferences >  Extension and turn off all extension. Quit and restart Safari. If this cures the problem, you know that one or more of your extensions is incompatible with Safari and needs to be updated or removed.
Also see this AppleKB about identifying and managing installed plug-ins:
You can also get a list of installed plug-ins from the Safari Help Menu:  Help > Installed Plug-ins

Safari plug-ins are located in the /Library/Internet Plug-Ins/ folder. The best way to remove one is to use an uninstaller for the plug-in if one were provided. Otherwise, you can select the unwanted plug in, CTRL- or RIGHT-click, and select Move To Trash from the context menu. Quit then restart Safari.

it's not just safari but i just quit safari and i open logos bible software and the same thing happened...

is there something wrong with the kernel or something i can do to fix that???
Can you open Activity Monitor, sort it by %CPU, so whatever is using the most is at the top, and post a screen shot?
Try this:

1. Go to About this mac under the apple in the upper left and click on More info
2. Click on system report
3. make a note of what it says after Model Identifier
4. go to your master drive – System -Library – Extensions – IOPlatformPluginFamily.kext -Contents – Plugins – ACPI_SMC_PlatformPlugin.kext – Contents – Resources – find the name from step 3 and move it to a folder that you can find again if needed.
3. Restart
i dont understand how to to get to the master drive system etc......not seeing that in my finder

So far what strung said seems to be working but I am monitoring it for now
There is a free utility for helping to diagnose Mac problems.
guys i now upgrade from 4 gig ram to 8 gig ram and the kernel task has gotten crazy again and using over 100 percent of cpu as shown in this screenshot and slowing down the mac drastically

i removed all my safari plugins and stuff but it still slow

ideas please????

If the problem went away after the fix I suggested but returned after adding new RAM, the first thing I would suggest is to re-do the fix.

If that doesn't solve the problem, there is a possibility your new RAM is faulty. Run the Apple Hardware Test:
How to redo the fix

Put back the desktop file where it was and then put it back on the desktop??
No. You will find there is now a new file by the same name in the same place. Put the one that is now in the desktop in the trash and move the new one to the desktop.
You may find Etrecheck useful, it is small, free, and designed to troubleshoot system problems.
Run without Safari open and again when you see the problem?
Google "etrecheck review" you will find it gets four and five stars in several reviews.
By all means, run EtreCheck and post the results back here for diagnostic purposes.
Ok i will run it and let you know

Btw I notice that especially when I am running flash video the CPU is pushed to the Max and the man starts to crawl

The video will be playing and sticking a lot or sometimes you just hear the audio and the video not really moving or moving out of sync

I'm not going to go over each of the sections of EtreCheck, but most of it just tells you what programs you have loaded and running on your system at the moment.

This one stands out to me.
NVIDIA GeForce 9400M - VRAM: 256 MB

It seems that you basically don't have enough video RAM.  Your 256 MB VRAM may not be sufficient for many the junk that commercial webpages make you load.   That may explain the kernel task pegging the CPU when you start Safari.  The CPU has to manage swapping data between System RAM and Video RAM.  I don't believe updating your flash player will improve things too much.

I suggest you install some sort of adblock, flash block, or noscript plugin combination to improve performance by blocking extraneous flash elements from loading.  Some obnoxious pages have multiple flash elements, and 256 MB of Video RAM isn't sufficient to run a lot of today's junk ware.  If they're not available on Safari, I suggest getting Chrome or Firefox and getting those plugins.  By having those plugins, I can have well over 50 tabs or pages open at the same time.  It's useful for research and backtracking when comparing things.

You could also just get a newer laptop.
Right now I have just an adblock plugin

I should get those other 2 plug-ins you mentioned????
Your Flash Player is way out of date. Before you do anything else, download the latest version from the link in my previous post and see if that solves your problem. Let us know. If that doesn't fix it we have some other suggestions.
Those others may or may not exist for safari.

Installing a new flash plugin might help a little, but that will still only help Safari as will my suggestions, not your Logos Bible software.

Your video RAM is just a bit too small for a lot of newer apps on Yosemite.
hey guys 1 quick question

could a bad fan be a result of this as well???

my fan used to be making loud noises and spinning most of the time at around 6200 rpm

I now  changed the fan and my mac seems to be running much more smoothly even if i am playing a video

could that be the cause as well???
Unlikely, overheating is more binary than analog, not overheating okay, overheating shutdown.
Video (or graphic intensive tasks) seems to be your problem area.
6 year old computer (with a good amount of memory) and a 6 year old graphic display system trying to display todays over the top graphic websites and high resolution video.
My guess is that you see no problems playing movies on DVD or stored locally.
It is when you mix the video demands with current web browsers and their code that you see the problems.
