This sounds like a wistful lunchtime daydream of a devoted science educator! Science used to be cool. It just so happened that the focus of their enthusiasm, the trendy thing to do, was… science.
Speed is the distance traveled divided by the time of travel. For example; if you were to travel a distance of 10 miles in 2 hours time, then your average speed equals 5 miles per hour. Most textbooks bold face the units that also contain direction information.
All quantities that are not vectors are called scalars. Time is a scalar quantity. The WWW links on this site will take you directly to the various web site pages. Your browser URL address line will tell you the origin of the site and it's material.
Let's talk a moment about unit conversions. It makes little difference what set of units you use.
The distance for example could be in miles, feet, or meters. Just be sure that you do the proper conversions. Also, be sure the units agree with one another. For example; Don't mix miles and meters in the same formula.
See our mathematics page for more information. Physicists use the SI system of measurement which uses meters as the basic length unit. In most cases it is much simpler to do calculations with SI units. If your distance is in meters and the time is in seconds then your speed answer will be meters per second.
Just do some thinking about the units your using. Yes, physics requires you to think. That's something you do all the time and it is not difficult. Acceleration is a change difference in speed divided by the time it takes to make the change.
If an object starts at rest then the velocity v0 at that time is zero.
