#### Transcript of MOTION

MOTION Graphing Film Creator In order to visually represent this graph through motion- In this case, we followed THOMAS THE TRAIN Conclusion From this experiment, we learned that
acceleration depended on speed and direction,
and found ways to represent different types
of acceleration, such as: HOT WHEELS LAB DOES THE HEIGHT OF A RAMP AFFECT THE DISTANCE A HOT WHEELS CAR WILL TRAVEL? CONCLUSION virtual lab What is the relationship between distance, speed, and time? INCREASING SPEED
OR ACCELERATION CONSTANT SPEED DECREASING SPEED
OR DECELERATION BOTH THE ROLLER COASTER AND TRAIN
EXPERIMENTS SHOW ACCELERATION,
IN THE TRAIN EXPERIMENT, THERE IS LINEAR MOTION AND THE SPEED AFFECTS THE ACCELERATION, WHILE IN THE ROLLER COASTER EXPERIMENT, THE MOTION IS CIRCULAR, AND THE DIRECTION AFFECTS THE ACCELERATION, WE DID 4 TRIALS FOR EACH # OF BOOKS WE USED TO ELEVATE THE RAMP, GOING FROM 1 TO 4 WE SAW THAT THE GREATEST
DIFFERENCE, ON AVERAGE, WAS BETWEEN
1 AND 2 BOOKS, WITH A DIFFERENCE OF
ABOUT 75 THE SMALLEST DIFFERENCE ON AVERAGE WAS BETWEEN 2 AND 3 BOOKS, WITH A DIFFERENCE OF ABOUT 55. Challenge Question:
Which car goes the middle distance?
caused the car to go father away from the starter point. This is because gravity has a stronger, more optimal force when at a higher, steeper angle, and observed that the car accelerated the most between 1 and 2 books. Doubling the initial height made more of a difference, or accelerated more, than when adding one book to 2, which made the least difference. We found that a greater slope for this experiment, we chose three cars, each with different speeds and race times, trying to find the correlation between distance, speed and time we noticed that the blue car, with the longest time [and the smallest speed], went the least distance The three cars that we selected were the blue, red, and purple cars. We predict that the red car will go the middle distance. Our prediction was accurate. The red car did travel the middle distance. the red car had the middle distance, but had the highest speed The fastest car does not always travel the farthest because the amount of time that they drive vary. The car that drives the longest does not always travel farther because they could have a slow speed, the purple car had the median speed and time, and went the farthest Conclusion: Using our data, we realized that the distance varied jointly as the speed and time--
a high speed and short time wouldn't lead very far,
and neither would a slow speed and long time,
however, a moderate speed and a moderate time would achieve an optimal distance, as would a high speed multiplied by a high time. In this case, it is better to be going 50 m/s for 5 seconds, than to go 100 m/s for 2 seconds. However, if there were a set distance, then the time and speed would vary, and, say it were a race where the finish line was set at 100 meters, the 100 m/s car would win.
