The speed of a car changes from 37ft/s 2 to 102ft/s 2 in five seconds. What is its acceleration in feet/second 2 (ft/s 2 )? Use the formula a = f – i/t, where a = acceleration, f = is final speed, i = initial speed and t = time.
Is a shorthand way of writing numbers using powers of 10. (Exponents!)
Scientific notation lets you know the size of a number without having to count digits.
You can write a number in scientific notation as the product of two factors.
7,500,000,000,000 = 7.5 x 10 12
The exponent is the number of times the decimal is moved so that it lies between the new ones and tenths place and the number to the left of the decimal is between 1 and 10.
