### Forces in motionpowerpoint

1. 1. Jackie Godden
2. 2. Demonstrate and explain how Newton's laws of Motion apply to the physical world. o LAW 1: Dominoes Lab o LAW 2: Dominoes Lab o LAW 3: Balloon Lab
3. 3. Demonstrate and explain how friction and gravity apply to Newton's Laws of Motion o Ramp Lab
4. 4. Demonstrate and explain the relationship between speed and acceleration o Dominoes Lab
5. 5. Demonstrate and explain how simple machines utilize mechanical advantage to transfer energy (potential, kinetic, and various others) o Rube Goldberg
6. 6. Demonstrate and explain how alternate forms of energy can be utilized to influence the united states energy needs o Persuasive Essay
7. 7. Problem: Does the amount of dominoes effect its over all speed and acceleration? Hypothesis: I believe that the more dominoes, the greater the speed. I think this because the more dominoes, the more force, and with more force, the faster the dominoes will travel.
8. 8.  20 dominoes  large flat space  ruler  tape  scrap paper  timer  a calculator
9. 9. 1. Gather all Materials 2. Line up 5 dominoes, separated evenly 3. Measure the distance from domino 1 to the last domino 4. Start the timer 5. Time until the last domino falls 6. Record data 7. find speed (distance divided by time) 8. Repeat steps 2-7 two times add 5 dominoes each time 9. Record all data
10. 10. IV: Dominoes DV: Speed CV: Spaced evenly, same distance apart, same surface, same timer, same dominoes
11. 11. Amount of Domino es Trial 1 Trial 2 Trail 3 Trial 4 Average time Speed 5 .32 .41 .49 .54 .44 36 cm per seconds 10 .37 .53 .43 .32 .41 43.9 cm per seconds 15 .18 .16 .39 .24 .25 84 cm per second
12. 12. Problem: Does the surface of the ramp effect the speed of the ball and how fast it falls? Hypothesis: I think that the surface will change the speed of the ball, because different surfaces cause a different amount of friction. I think that the trash bag-covered ramp will have the fastest time. I think this because the trash bag isn't clinging, like the smooth surface, and it isn't ruff like the towel. I predict that the towel will have the slowest time because of its ridges and its ruff texture. I also think that the faster the ball rolls down the ramp, the faster gravity will pull it to the ground.
13. 13.  1 tote lid  1 large tote  1 small tote  1 trash bag  1 tennis ball  Tape  Towel  Flexible sled for smooth texture  2 timers
14. 14.  Gather all materials  set up both totes  Position tote at desired angle  Tape trash bag to tote  Roll the ball  Time its roll  Time its fall of the edge(for seed of gravity)  Recode data  Repeat 5-8  Repeat 5-8  Remove trash bag  Tape towel  Repeat 5-8 (3 times)  Remove towel  Tape sled(smooth surface)  Repeat step 13
