Prop to Acc Equilibrium Rule F = 0 Chapter 3: Linear Motion (Exercises: 3,6,8,20,28,29 Speed: S= D/T V= gt Average Speed = total distance covered/time interval Instantaneous Speed: Speed at any instant (car speed) Velocity: D/t Constant: Fnet=0, Acc=0 Vector Quantity : Quantity with magnitude and direction Acceleration: a = net force/mass (F net /m) A= V/ time interval of gravity: 10 m/s Free Fall- under gravitational influence only Velocity from rest: V=gt Distance from rest: d=1/2gt 2 Time when d known: t= (2d/g) Ch. 4: Newtons Second Law of Motion (Exercises 1,3,14,19,26,28,29,32,33,34,41,59) Acceleration= Change in V/time interval Friction Force Answer: direction, type & amount Mass (N) Weight (Kg) x 10 = N Kilogram (x 100,000 = g) Newton (N) Newtons Second Law: acceleration of an object is directly proportional to the net force acting on the object,...
