 Equations for uniformly accelerated linear motion x = xo + vot + (1/2)at^2 v = vo + at v^2 = vo^2 + 2ax v(avg) = (1/2)(v + vo) Distance vs Time graph (d/t) -Slope is velocity -Area under the curve is meaningless Velocity vs Time graph (v/t) -Slope is acceleration -Area under curve is displacement Displacement x = v(avg) * t Acceleration a = (v - vo)/t Peak height of a projectile vo*sin(theta) = sqrt(2gh) Factors that change air resistance Speed, surface area, shape Mass and Air Resistance -Air resistance has less effect on a more massive object -However, it does not CHANGE air resistance Inertia The tendency of an object to remain in its present state of motion (EX: massive object will accelerate more slowly) Newton's Third Law forces NEVER act on the ______ _______. same system The normal force on an inclined plane is: mgcos(theta) The net force due to gravity and the normal force on an inclined plane is: mgsin(theta) Centripetal Force (m*v^2)/(r) always caused by another force (either gravity, electromagnetic, or contact forces) T or F: Friction always opposes motion F: Friction always opposes relative motion. The vector points in the direction that would prevent surfaces from sliding past each other Force of Static Friction fs <= us*Fn Force of Kinetic Friction fk = uk*Fn Hooke's Law F = -k*dx
