Study Notes

Measurement and Motion

  • A stopwatch is accurate for one specific measurement, which is time, and can measure time reading to 0.1s or better.

Speed and Velocity

  • Speed is defined as the distance traveled per unit time.
  • The equation for speed is distance ÷ time.
  • Velocity, on the other hand, is defined as the speed in a given direction.
  • Velocity is a physical quantity that has both magnitude and direction.

Scalars and Vectors

  • Speed is a scalar quantity, which means it has magnitude only.
