Journal Entry 13

We did not test the car today due to the fact that the spring is wearing out and we want our car to go at least one lap. Instead, we worked on our force diagrams and our website.

We also discussed Scientific Notation. Scientific notation is used to make numbers easier to read. For example: if someone had a decimal, say .0000853, in scientific notation, that number would be 8.53x10^-5. This is because you move the decimal over to the first integer and because the decimal is going 5 spaces to the right, the exponent in the notation is going to be -5.

Another example would be if you had a whole number such as 19,050,000, the scientific notation would be 1.905x10⁷. This is because you move the decimal to the first integer and because the decimal is going 7 spaces to the left, the exponent in the notation is going to be positive 7.
