Definition
 The angle subtended at the center of a circle by an arc of length equal to the circle's radius
Term
 Specific Latent Heat of Vaporisation
Definition
 The quantity of energy per unit mass required to change a substance at constant temperature from a liquid into a vapor
Term
 Specific Latent Heat of Fusion
Definition
 The quantity of energy per unit mass required to change a substance at constant temperature from a solid into a liquid
Term
 Simple Harmonic Motion
Definition
 Acceleration is directly proportional to the displacement, and in the opposite direction to the displacement
Term
 Resonance
Definition
 The build up of a large-amplitude oscillation when the frequencies of the vibrating objects match
Term
 Principle of Conservation of Momentum
Definition
 In any direction, in the absence of external forces, the total momentum of a system remains constant
Term
 Specific Heat Capacity
Definition
 The quantity of thermal energy required to raise the temperature of a unit of mass of a substance by a unit temperature rise
Term
 Impluse
Definition
 Defined as FΔt. It equals the change in momentum of a body- also equal to the area beneath a force/time graph
Term
 Boltzmann Constant
Definition
 The gas constant for a single molecule. k = 1.38 x 10²³ Jkˉ¹
Term
 Internal Energy
Definition
 The sum of the random distributions of kinetic and potential energies of all the molecules in the body
Term
 Ideal Gas
Definition
 A gas that has internal energy only in the form of random kinetic energy
Term
 Boyle's Law
Definition
 The volume of a fixed mass of gas is inversely proportional to the pressure exerted on it, provided the temperature is kept constant
Term
 Kepler's Third Law
Definition
 The period of a planet squared is directly proportional to the mean radius of it's orbit cubed. T²∝r³
Term
 Gravitational Field Strength
Definition
 At any point it is the force acting per unit mass at that point
Term
 Ideal Gas Temperature
Definition
 For a fixed mass of an ideal gas at constant pressure, its volume (V) is proportional to the ideal gas temperature. V∝T
Term
 Ideal Gas Equation
Definition
 pV=nRT // pV=NkTp=pressure; V=volume; n=no. of moles; R=gas constant; T=absolute temp
Term
 Newton's First Law
Definition
 A force is necessary to change the state of rest or uniform motion in a straight line of a body
Term
 Newton's Second Law
Definition
 The rate of change of momentum of an object is directly proportional to the net force acting on it
Term
 Newton's Third Law
Definition
 When body A exerts a force on body B, then body B exerts a force on body A that is equal, opposite in direction, and of the same type
Term
 Newton's Law of Gravitational Attraction
Definition
 The gravitational force of attraction between two bodies is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them
Term
 Linear Momentum
Definition
 Defined as the mass of an object multiplied by its velocity. p=mv
Term
 Kilowatt Hour
Definition
 1kWh is the energy used/provided by a 1kW device in 1 hour
Term
 Angular Frequency
Definition
 The product of 2π and the frequency, or 2π divided by the period
Term
 Amplitude
Definition
 The maximum displacement
Term
 Avagadro Constant
Definition
 N(A) = 6.02 x 10²³ molˉ¹
Term
 Circular Motion
Definition
 Force acting towards the center of the circle, perpendicular to the velocity
Term
 Damping
Definition
 Deliberately reducing the amplitude of an oscillation
Term
 Displacement
Definition
 The distance an object has moved from it's mean (equilibrium) position
Term
 Equilibrium
Definition
 The net force is zero. i.e. weight = reaction force
Term
 Frequency
Definition
 The number of oscillations per unit time at any point
Term
 Field
Definition
 The region in which a force operates
Term

 Contains 6.02 x 10²³ particles
Term
 Newton
Definition
 The force that gives a mass of 1kg an acceleration of one meter per second every second
Term
 Period (Circular Motion)
Definition
 The time taken for the object to complete one revolution. It is related to the speed (v) and the radius (r) by: v =2πr/T
Term
 Perfectly Elastic Collision
Definition
 A collision in which no momentum or kinetic energy is lost
Term
 Period (Planet)
Definition
 The time it take to complete one orbit. For the Earth it is one year
Term
 Period (S.H.M.)
Definition
 The time for one complete pattern of oscillation to take place at any point
Term
 Phase (State)
Definition
 Whether the substance is a solid, liquid or gas
Term
 Thermal Equilibrium
Definition
