"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)

Free End vs Fixed End on Spring

Image
Here's what a free end of a spring looks like: (The end of the string is free to move loosely) When a force is applied on one end of the slinky and the wave travels to the other end, the wave "bounces back" and move back towards the direction it came from on the same side of the slinky. This is because of the forces acting on the slinky as it travels towards and goes through the free end of the slinky. As seen in the diagram, at the 5th dot, the net force is pulling upwards because the end of the slinky is not tied to a pole to counteract that upward force, resulting in the wave to continue the pattern on the same side of the slinky but in opposite directions. Here's what a fixed end of a spring looks like: (The end of the string is fixed and cannot move loosely) When a force is applied on one end of the slinky and the wave travels to the other end, the wave "bounces back" and move back towards the direction it came from on the opposite

SPOOKY ELECTRIC FORCE

Image
Kicking off the new school year, we started off with the electrical force, not to be confused with magnetic force, which deals with magnets. As for the electrical forces, it’s like a spooky force since it’s not a force applied by an object, but more of something that is intangible, hence SPOOKY. The electrical force is just a force between something that is positively charges (lower number of electrons compared to protons) to something that is negatively charged (higher number of electrons compared to protons). When a balloon rubs against my hair, it collects excess electrons from my hair and transfers onto the balloon. Whatever side my hair rubbed against the balloon means that that area is now negatively charged. NOTICE HOW THERE NEEDED TO BE FRACTION IN ORDER FOR THE NEGATIVE CHARGE TO SEPARATE FROM MY HAIR TO THE BALLOON. I think of the friction as energy added to the system in order to get the electrons to move and to go onto the balloon. When using the bottom tape (negative char

Challenge Activity (Parabolic Motion)

Image
What happened: A challenge activity that we did in class was set up with a diagonal ramp connected to a horizontal ramp that was set up on a table. Beside that table was a cup that the marble needed to land in. The goal of the challenge was to find out where to release the marble on the diagonal ramp so that it ultimately ends up landing into the cup. However, we were not allowed to test drop the marble at different places on the ramp to see where it would go.  During the process, my group tried to calculate the acceleration of the marble going down the horizontal ramp and the time it takes. We did this by finding the mass of the marble, finding the angle degree of the diagonal ramp, and by test dropping the marble from the horizontal ramp (but catching the marble right when it got to the horizontal ramp) and timing it. Our group realized right when the marble gets onto the horizontal ramp, the velocity would become constant (because the marble in not moving at an angle). However,
