Acceleration is the change in an object’s velocity over time. It is calculated using the formula: acceleration = change in speed/time interval.
This formula will be useful in your fuel cell car science fair projects.

When you work on a physics science fair project you need to utilize common formulas to analyze the data that you collect. One formula that you will most likely need to use is the formula for speed. This formula is:
Speed = distance/time
You can use this formula for fuel cell car science fair projects.

If you need to collect data that involves length measurements then these conversion factors will be helpful:
1 centimeter = .394inches
1 meter = 39.4 inches
1 meter = 3.28 feet
1 kilometer = .621 miles
You may need to use length measurements in your fuel cell car science fair projects.

Multiples of SI units are very important to understand when you are collecting data that have large measurements. Some of the most common prefixes for multiples of SI units include: hecto- which is 10^2 power, kilo- which is 10^3 power, mega- which is 10^6 power, giga- which is 10^9 power and tera- which is 10^12 power.
Use these prefixes to simplify your data summaries for your energy science fair projects

It is important to understand the prefixes used to describe subdivisions of SI units. For example, pico- means 10^-12 power, nano- means 10^-9 power, micro- means 10^-6 power, milli- means 10^-3 power and centi-means 10^-2 power.
Keep these prefixes in mind when creating your own energy science fair projects
