Newton"s laws (vector constraint - 2 equation per particle in 2d: work- energy & conservation of energy (scalar constraint - 1 eqn/particle) Unc = t + vg + ve = etot. Particle kinetics: conservation of energy: conservative forces. Forces for which work done on a mass (particle) depends only on the initial & nal positions and. Not on the path between the two positions. m v. Movement of a mass back to its original position returns it back to its original state of motion in that position! N o n c o n s + u. Uconservative has the potential to store energy which can be returned to the particle as it moves through different positions. N o n c o n s = t u. Particle kinetics: conservation of energy: typical conservative- potential energy forces.
