Matt, I'm just throwing in all of the notes, we can simplify this later on

Physics Lecture

Vectors

Plenty of measurements in physics require both magnitude and direction to be accounted for. These are called vectors, and are represented as arrows.


Motion

Changes in an object's location or position over a period of time. Several measurements in motion are vectors:

  • Displacement (from starting to destination point)
    • d=vt
      • Distance can be measured in feet or meters
  • Velocity (speed with direction)
    • v=d/t
      • Velocity can be measure in ft/s or m/s
  • Acceleration (how quickly does the velocity change?)
    • a=v/t
      • Acceleration can be measured in ft/s^2 or m/s^2
There are a few types of motion
Linear (1D, straight line)
Parabolic (2D, including gravity)
Rotational (turning around an axis)
Circular (revolution, not rotation)
Periodic (oscillations, back-and-forth)

Forces

A mass of any kind requires an unbalanced force in order to change its motion(accelerate)

Forces are vectors that result in the motion of objects when they are unbalanced
