Physics

• Velocity

  Defined as the rate of change of displacement with respect to the elapsed time
• Acceleration

  Defined as the rate of change of velocity with respect to the elapsed time
• Pythagorean theorem

  This theorem is used to get the magnitude of a vector with horizontal and vertical components
• Projectile motion


  a simple two-dimensional motion with a parabolic path or trajectory
• kg-m/s


  SI unit for linear momentum
• Ampere(A)

  SI unit for current
• Voltage (V)

  SI unit for voltage
• Ohm

  SI unit for resistance
• Least count


  Smallest possible measurement of the device
• Uncertainty 


  Half the least count for analaog device and the least count itself for digital device
• Systematic errors


  Errors in measurement due to limitation of the instruments
• Random errors


  Errors due to the limitations of the researcher's skill in handling instruments, and fluctuation in environmental conditions
• Tail to tip method


  Method for adding vectors
• cos = adjacent/hypotenuse
• sine = opposite/hypotenuse
• Charles Augustine Coulomb


  French Scientist showed that there is a force electric between two subjects
• Gay-Lussac's law


  States that at constant volume and amount of gas, the pressure is directly proportional to the absolute temperature
• Boyle's law

  The space filled or the volume of a gas is inversely proportional to the pressure at constant temperature
