  • Wavelength Lab
  • In this experiment, I don’t think there is not so much error. The reason for this is because we can only make an error in the measurement. The room temperature, humidity may cause some changes but I think in this experiment, we don’t have much effect by thes..

  • Newton`s Second Law
  • Aim ; Determine the relationship between mass, force and acceleration.  F = m*a (net force = mass times the acceleration)  2. First, we did the experiment that we change “Force”. We do not change the “Mass”. Only change the “Force”. We decided to ta..

  • Elastic and Inelastic Collision
  • I think momentum will conserve in both elastic and inelastic collisions. In last lab, we conserved that both carts’  momentum came out to be almost the same. I think this time also will be conserved and it will be come out to be  same. So, if make a graph, ..

  • Momentum Lab
  • Aim ; What is the relationship between momentum of 2 carts in an explosion? Momentum = Mass × ΔVelocity  List of problems.  1. Movement (slide) of additional weights on the cart. ・ We used cylinder shape weights for additional weights, so when the c..

  • Determine the force of gravity
  • This experiment’s purpose is to determine the force of gravity using a simple pendulum. A simple pendulum consists of a heavy weight called the bob, supported from a fixed point about which the bob is free to swing by a string of insignificant mass. To calcul..

  • 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..

  • How does the temperature of carbonated beverage affect its acidity (pH)?
  • >>> INTRODUCTION Determine the relationship between the temperature of carbonated beverage and its acidity. We feel acid is strong when the soda is really cold. On the other hand, even the exact same type of soda, we feel acid is weak when the drink is warm. ..
