"Speeding Up"
.jpg)
Over the past few classes, we have discussed about speeding up graphs and the equations that go along with it. So far I can conclude(?)... 1. Speeding up graphs are quadratic graphs 2. m= m/s^2 s^2 + m/s s+ m means... m= speeding up + average velocity? + starting position 3. m/s= m/s^2 s + m/s means... m= speeding up + starting velocity #3 EQUATION 1st TERM= ACCELERATION RATE 4. P=0.365t^2-0.132t-0.127 V=0.740t-0.143 The 1st two terms match ( 0.365t^2 and 0.740t) The two 2nd terms match ( -0.132t and -0.143) 5. Speeding up= change of velocity/ time Questions: What does the second term of the speeding up equation mean? Is it average velocity? Is there a "maximum acceleration"? (a point where the object cannot accelerate any more) More: Magic Tria
