Study Notes
- Physics Exam 5
Introduction System
- Preference System is defined by the point of origin
- Distance traveled is represented as d = S - So
M.R.U./U.R.M (Uniform Rectilinear Motion)
- Movement occurs across a straight line
- Uniform means constant velocity (cte)
- Velocity is constant
U.A.R.M.
- Motion is accelerated and rectilinear
- Acceleration is constant
Formulas
- X = Xo + Vot + ½a*t²
- V = Vo + a*t
- V² = Vo² + 2a(X - Xo)
Position and Speed
- Position changes along a trajectory over time
- Speed is represented as v = d/t (m/s)
- Average velocity is represented as Vm = d/t
