  • Circular Motion Lab
  • < AIM > Determine how does the velocity of an orbiting body depend on the radius of the circle under constant centripetal acceleration.  First, I thought that the velocity would decrease, when we increase the radius of the circle under constant centripetal ..

  • Boyle`s Law
  • Aim:  Determine the relationship between the gas and the volume in the gas syringe, by using a “Gas pressure sensor”. (Which means, prove Boyle’s Law)  Aim of this is to prove the Boyle’s law. From out #1’s data table, we got very close value of consta..

  • Experiment about Fireworks.
  • Determine the kinetic energy of the rocket firework by calculation. To calculate kinetic energy, 2 values are need. How high it went and how long it takes to reach zenith. Use a method call triangulation to determine how high the rocket firework went. It’s ve..

  • Transformation matrxi
  • Introduction. A linear transformation, T, of the plane which maps the point P (x, y) onto the point P’ (x’, y’) is defined by the equations...  First, it’s easy to think about so make it the coordinate of OABC as same as Part 1’s b). Which is O = (0, ..

  • Investin Sequence
  • From the question above, we can see that for n = 1, we will get 1 x 1! by the equation. And for n = 2, we have 2 x 2! and identically, we have 3 x 3!, when n = 3. There is a simple pattern. So, we can understand that the n x n! is the formula for the nth ter..

  • Rotating Angles
  • A rectangle OABC rotates counter clockwise about the point O as shown in the diagram below, which is not drawn to scale  Initially O is at (0,0), A is at (4,0), B is at (4,3), C is at (0,4).  The diagram shows the rectangle after it has rotated through 20 ..

  • Population Growth
  • First, the graph of the population versus time is about direct proportional. However, if we see the changes (difference between years), we can see the some differences. First, between 1801 and 1811, there is least population increase in the chart. Between 1811..

  • Heats of Reaction
  • *Aim According to Hess’s law, the heat of reaction of the one reaction should be equal to the sum of the heats of reaction for the other two. Measure the heat released by 3 reactions by using a Styrofoam-cup to than calculate for the heat of reaction, ΔH, fo..
