Particle Kinetics – Newton’s 2nd Law Force Interaction between a body and its environment; action of one body on another. Force is a vector characterized by magnitude, direction, and the point of application . Superposition of forces: 123 1 2 3 1 2 3 , x xxxx y yyyy R FFF F R F F F F = Σ = + + + = Σ = +++ = Σ =     R is called the resultant, the total force, or the net force, which has the equivalent mechanical effect as the combination of the individual forces. Newton’s laws of motion 1. Newton’s first law (law of inertia): A body will remain its state of motion if and only if there is no net force acting on it: 0 0 constant equilibrium Fa υ Σ=⇔=⇔= If the body is initially at rest, it will remain at rest. If the body is in motion, it will move with constant velocity. Inertia: the tendency of the body to remain its original state of motion, the resistance to change of motion.
