Scientific Notation and Universal Gravitation

What is the symbol highlighted in yellow?

• a comma (,)
• a decimal (.)

Is this the correct place to start when doing scientific notation? Why or why not?

• No; you do not start on the comma
• Yes; this is the decimal point, which is where you start moving for scientific notation

If you were to convert 80,675 to scientific notation, where would the DECIMAL move?

• It would not move (stays 80,675)
• It would move to make a smaller number (becomes 8.0675)
• It would move to make a smaller number (becomes 0.80675)
• It would move to make a larger number (becomes 806,750)

What is the difference between converting 164 and 0.164 to scientific notation?

• The first (164) will be converted to 1.64, the second (0.164) will be converted to 16.4
• The first (164) will have a positive exponent, the second (0.164) will have a negative exponent
• There will only be a difference in the exponent value, not the sign (2 for 164, 1 for 0.164)
• There will be no difference

How do you write this number in scientific notation? The first two steps (identifying the decimal point and moving it to make a number between 1-10) have been done for you.

Two planets are 2.14 x 10^5 meters apart. What happens to the force of gravity (Fg) if they move closer together?

• it increases because decreasing distance increases the force of gravity

• it decreases because decreasing distance decreases the force of gravity

• it increases because increasing mass increases the force of gravity

• it decreases because decreasing mass decreases the force of gravity
