"Speeding Up"
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)
