1. When a young typhoon develops hot towers of rapidly rising warm air, what will happen to the strength of the typhoon?
2. What is the importance of the sinking salty brine water under the ice of Antarctica?
3. __________ __________ For the Desmos graph and regression, determine the acceleration of gravity g.
   
4. __________ __________ Using an acceleration of gravity g = 980 cm/s² and d = ½gt², how far will a ball fall in 3 seconds?
5. __________ __________ Using an acceleration of gravity g = 980 cm/s² and solving d = ½gt² for t, calculate how many seconds for a ball to fall 1960 cm.
6. A marble with a mass of 5.0 grams is 20 centimeters above a table on an orange plastic track. The marble is released and rolls down the ramp onto the table. Use an acceleration of gravity g equal to 980 cm/s² for this question.
   1. __________ __________ Calculate the Gravitational Potential Energy of the marble before the marble is released using the formula GPE = mgh.
   2. __________ __________ The kinetic energy at the bottom of the ramp should be equal to the GPE the marble had at the top of the ramp. Solving Kinetic Energy KE = ½mѵ² for ѵ, calculate the velocity that the marble should have at the bottom of the ramp.
   3. __________ In the laboratory using an actual marble and the orange track, will the marble have the speed you just calculated?
   4. __________ Will the actual marble speed be faster OR slower than you have calculated?
7. A student rolled marbles into a line of five marbles.
   
   1. What happens when one marble is rolled into five marbles on a ruler track?
   2. What happens when two marbles are rolled into five marbles on a ruler track?
   3. How is the number of marbles rolling into a line of marbles related to the number rolling out of a line of marbles?
   4. What happens with the outbound marbles when the marble(s) roll into a line of marbles slowly? Slow roll in...
   5. What happen with the outbound marbles when the marble(s) roll into a line of marbles quickly? Fast roll in...
   6. What is the name of the physical science law are the marbles obeying?
8. Provide definitions for the following:
   1. Newton's first law of motion.
   2. Newton's second law of motion.
   3. Newton's third law of motion.

      Why?
      
      
   2. _______________ Based on the data above, which variable has the least effect on the force of friction?
      Why?
