Laws Of Physics
Newton's first law of motion: an object will continue in a state ofrest or uniform motion in a straight line unless an eternal forceNewton's second law of motion: the rate of change of momentum of anobject is directly proportional to the force acting, and takes placein the direction in which the force acts.Newton's third law of motion: To every action there is an equal butLaw of conservation of momentum: When two or more objects act on eachother, their total momentum remains constant, provided no external
Kinetic Theory of matter: all matter is made up of tiny particlescalled molecules, which are constantly in motion, attract each otherstrongly when close together. (pV = constant)Combined Gas equation: for a fixed mass of gas: pV/T = constant. (V/T = constant)Boyle's Law: the pressure of a fixed mass of gas is inverselyproportional to its volume provided the temperature of the gas iskept constant. across its ends provided the temperature andother physical conditions remain constant. Right-hand Grip Rule: thumb points to N pole / RIGHT hand aroundsolenoid / fingers indicate conventional current. Young's Experiment: l = sw/D (s = distance btw centers of parallelslits / D = distance from slits to eyepiece scale / w = distance btwcenters of two neighboring fringes). Ohm's Law: the current flowing through a metal conductor is directlyproportional to the p. (p/T = constant)Charles' Law: the volume of a fixed mass of gas is directlyproportional to its absolute temperature provided the pressure of thegas is kept constant. Pressure Law: the pressure of a mass of gas is directly proportionalto its absolute temperature, provided the volume of the gas is keptconstant. Further Notes:Formulas:Power = W/t = E/tPressure = F/A = rgh (r = density / h = height) forpressure in a liquid)Refraction: light passing into an optically more dense medium is benttowards the normal; light passing into an optically less dense mediumis bent away from the normal. vation of energy: energy cannot be made or destroyed,but it can be changed from one form into another. Fleming's LEFT Hand Rule: to find the direction of the force: Thumb =force / First Finger = Field / seCond Finger = CurrentFleming's RIGHT Hand Rule: to find the direction of the inducedcurrent.
