Abstract :The purpose of the experiment is to explore elastic and inelastic collisions in order to study the conservation of momentum and energy. The guided track‚ carts‚ photogates ‚ 250 g weight and picket fences were the primary components used in the procedural part of the experiment. Each experiment involved the use of the photogates and picket fences to measure the initial and final velocities of both carts when they collide. The data was collected and translated to a graphical model for further

force of gravity. - Surfers rely on weather conditions‚ their equipment‚ safety‚ and their techniques. - Low tide waves are faster‚ stronger‚ and tend to close-out - High tide waves are slower‚ and lose force. • Surfing has a wide background of physics • The amplitude in a wave grows as energy is added to it‚ and it shrinks when energy is subtracted from it. - The speed of the wave‚ and the buoyancy of the board is what keeps the ability to ride the wave and maintain speed. - When you are surfing

Lecture notes by Prof. A. K. JAIN‚ IIT ROORKEE CHAPTER 13: The Deuteron (Lecture time: 2 Hours) Deuteron is the simplest nuclear system where nuclear forces come into play. It is the “Hydrogen Atom” of nuclear physics. It may also be viewed as the simplest odd-odd nucleus‚ having one proton and one neutron. It exhibits features which require the use of a number of new concepts such as exchange force‚ tensor force etc. Of three possible states of two nucleon system‚ di-neutron‚ di-proton‚ and deuteron

Conclusion: Category 1: Momentum was found that after the collision was less than before the collision by 10%. This was not what has been expected‚ so the difference was fairly significant. This happened because of friction‚ when the two pucks collided‚ they have lost a bit of their momentum‚ so the momentum after the collision differed. Kinetic energy differed more than what was expected‚ it was significantly less after the collision‚ the difference before and after the collision was 63.7%‚

Required Vocabulary – IB 12 Higher Level Physics and Physical Measurement 1. Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

Gatto and Holt In the essays “Against School” by John Gatto‚ and “How Teachers Make Children Hate Reading” by John Holt‚ both authors discuss their views on education and schooling. In both essays the authors analyze education and state their opinions about what is wrong with our schooling system. The authors explain the issues surrounding teachers‚ teaching styles‚ and curriculum in our schools. In John Gatto’s essay “Against School‚” he explains how he does not believe that forced schooling
