Document Summary
X = x0 + vox*t + (1/2)*ax* t2. X - xx = ((v0x + vx) / 2) *t. Perpendicular component of a changes direction of v. Parallel component of a changes magnitude of v. X = (v0 * cos( 0)) * t. Y = (v0 * sin( 0)) * t - (1/2)*g*t2. Vy = (v0 * sin( 0)) - g*t. ) = v y / vx (x 2 + y2) (same for velocity) A body acted on by no net force moves with constant velocity and zero acceleration. Body in equilibrium: sum of forces equals 0. F(a on b) = -f(b on a) Apparent weight n = m* (g + a) W = k2 - k1 = k . Springs in series (in line with each other): Springs in parallel kparallel = k1 +k2. K1 + u1 + wother = k2 + u2. If sum of external forces on system is zero, momentum is conserved.
