 What are the big five kinematic equations? d = 0.5 (v_i + v) t v = v_i + a t d = v_i t + 0.5 a t^2 d = v t - 0.5 a t^2 v^2 = v_i^2 + 2 a d missing: A dog finally in tears sqrt(2) 1.4 sqrt(3) 1.7 cos30 sqrt(3)/2 Newton's Laws 1) Fnet = 0 => a=0 => v = constant 2) F_net = m a 3) F_2on1 = -F_1on2 F_grav and g F_grav = w = m g F_grav = G M m / r^2 => g= G M / r^2 Incline Plane (theta=incline angle to horizontal): 1) Force due to gravity parallel to ramp 2) Force due to gravity perp to ram 1) m g sin(theta) 2) m g cos(theta) = Normal Force Static friction (max) Kinetic friction F_f, static MAX = u_s F_N F_f, kinetic = u_k F_N Center of Mass (=Center of Gravity) x_CM= (m1 x1 + m2 x2 + mn xn) / (m1 + m2 + mn) = (w1 x1 + w2 x2 + wn xn) / (w1 + w2 + wn) Torque torque = r F sin(theta) = l F l is the lever arm. Momentum : general p = mv Momentum: impulse J = F t Momentum: Impulse-Momentum theorem J = delta(p) Momentum: Conservation of Momentum total p_i = total p_f Uniform Circular Motion: centripetal acceraltion a_c = v^2 / r Uniform Circular Motion: centripetal force F_c = m a_c = m v^2 / r Work W = F d cos(theta) where theta is the angle between F and d; work is a scalar quantity. Force that acts through a displacement d. Kinetic Energy KE = 0.5 m v^2 Work-Energy Theorem W_total = delta(KE) Power P = W / t ; P = F v, if F is parallel to v PE_grav PE_grav = m g h (if h<
