Each audio format intended for DVD has different compression ratio and quality. There are three main types of audio: AC3 (Dolby Digital), PCM (uncompressed), and MP2 (MPEG Layer II). The most common quality of audio in DVD is 48hz (frequency), with Dolby Digital 5.1 (surround sound).
AC3
It's a Dolby Digital Audio. AC3 supports not only stereo, but also surround. Audio bitrate range: from 128Kbit/s to 384Kbit/s. 192Kbit/s is the most common bitrate.
Surround sound must have at least 6 separate source channels. Taking a stereo or mono audio file and forcing it into Dolby 5.1 format will only waste space and provide no advantages.
Pros: AC3 format has very good quality, surround sound support and very high level of compression. That's why the size of audio information is small.
AC3 is the best format to use in DVD
PCM
Cons: The main disadvantage of Uncompressed PCM (WAV or AIFF) audio format is size. It stores all audio information without compression. It's a recommended format for audio editing. Do not use PCM in final versions of DVD. Only leave it as PCM if final disc size is unimportant or if unusual distortion occurs from AC3 or MP2 compression. Common bitrate is 1536k.
Pros: The main advantage of the PCM audio is excellent quality. With PCM you can preserve all audio frequencies (even outside the range of human hearing).
MP2
Another form of MPEG audio is MP2. Also known as MPEG Layer II and .mpa files. This format is not officially supported for NTSC video. If you have MP2 audio then do not recompress it to AC3, recompression may destroy the quality. So, leave it untouched. But if you have PCM uncompressed source, I definitely recommend to use AC3 instead of MP2. Common bitrate is 256Kbit/s.
Pros: The main advantage of MP2 is good compression level and ease of audio conversion from SVCD or VCD.
Cons: The main disadvantage of MP2 is not very good quality, and lack of support by all devices.

For the highest resolution videos (1080p/720p) or 'Blu-ray', MPEG-2 and H.264 are the best codecs. MPEG-2 will usually have the file extension .m2v, and H.264 will usually have .m4v

Ill say, no you cant. Own a Gigabyte 9800Gt Silent Cell. Have some problems with a stalling computer after a while playing games. I quess you can, but its not recommended.
Here are several video file extension names (formats):.avi, dvr-ms, .m1v, .mp2, .mp2v, .mpe, .mpeg, .mpg, .mpv2, .wm, .wmv
Studio 14 can import the following video file formats with the allowable extensions for each format noted in parenthesis:AVI File - (.avi)MPEG Files - MPEG-1, MPEG-2 SD & HD, and MPEG-4 - (.mpg, .mpeg, .mod, .mp2, .mp4, .m2ts, .mts, .m1v, m2v. mpv)WMV Files - (.wmv)DIVX - (.avi)MOD (JVC Everio cameras) - (.mod)3GPP Files - (.3gp)TOD Files - (*.tod)AVCHD - (.m2ts, .mts) - Requires Ultimate or Ultimate CollectionNote: Studio does not support DVR-MS Files.
First, know that p = mv, where p = momentum, m = mass, and v = velocity. Let Car A be the car with twice the mass, and Car B be the car with twice the velocity. The momentum of Car A has to be in relation to the momentum of Car B, so: Car A: p = mv write the equation p = 2mv write the equation in relation to Car A p = 2(mv) realize that the new equation is twice the old 2p Car B: p = mv p = m2v p = 2(mv) 2p So the cars have the same momentum!
Well technically you can use the same equation for elastic collisons to find the velocity. (first mass*its velocity)+(secind mass*its velocity)=(first mass*new Velocity)+(second mass*new velocity) OR... if its inelastic the seccond half of the equation can look like: (first mass+second mass)*Final Velocity and the formula for kinetic energy is: .5mv^2
