PSc 1051: Review Basics

    1. Scientific Method
      • Can you describe the different elements constituting the scientific method?
      • What is meant by observation and identifying patterns? What is important for the process?
      • What is a hypothesis and a theorem?
    2. Units
      • An answer of 200 is not sufficient (200 meters or 200 kilometers?)
      • What are the fundamental units in the SI system?
      • Do you understand scientific notation?
    3. Defining equations
      • velocity = (change in distance)/time [units = m/s]
      • acceleration = (change in velocity)/time [units = m/s]
      • force = massacceleration [units = kg-m/s 2 ]
      • work = forcedistance [units = N-m]
      • pressure = force/area [units = N/m 2 ]
      • gravity is an example of acceleration [g = 9.8 m/s 2 ]
      • weight is an example of a force [W = massg]
    4. Newton's Laws
      • 1Law: defines inertia
      • 2Law: F = ma
      • 3Law: for every force, there is a reaction force
    5. Energy
      • Work is an example of energy
      • Energy can be stored (potential energy)
      • Motion is a form of energy (kinetic energy)
    6. Temperature
      • Temperature is a measure of the internal energy of an object
      • Can you convert from Fahrenheit to Celsius?
      • Can you convert from Celsius to Kelvin?
      • T = 0 K (zero Kelvins) means zero internal energy
      • There are no negative temperatures as measured in Kelvins
