Term
 Constant motion (velocity)
Definition
 speedvelocity = ------ time
Term
 Acceleration
Definition
 change in velocityAcceleration ------------------ time
Term
 Weight and mass
Definition
 Weight = mass X gravity
Term
 Density (P) in kg/m cubed
Definition
 Mass Density = ------ Volume
Term
 Force in Newton
Definition
 Force= Mass X Acceleration
Term
 Terminal Velocity
Definition
 Weight of object (downwards) = air resistance (upwards)
Term
 Hooke's Law
Definition
 Force = Spring constant X extension
Term
 Momentum of a force
Definition
 momentum of force = force X distance from pivot
Term
 Equilibriam
Definition
 Total clockwise movment = Total anticlockwise movment
Term
 Work done in Joules (J)
Definition
 work done= Force X distance covered by object
Term
 Kinetic energy in Joules (J)
Definition
 Kinetic energy = 1/2 X Mass X Velocity squared
Term
 Potential energy in Joules (J)
Definition
 Potential Energy = Mass X Gravity X height
Term
 Law of conservation of energy
Definition
 Energy can nver be created or destroyed only transfered
Term

Definition
 Work done Power = ----------- Time taken
Term
 Pressure in Pascal (Pa)
Definition
 ForcePressure = ------- Area
Term
 Pressure due to liquid
Definition
 Pressure= Density X Gravity X Height
Term
 Pressure and volume relationship(Boyle’s law)
Definition
 P1 X V1 = P2 X V2
Term
 Thermal Expansion (Linear)
Definition
 Change in length = Linear expansivity of material X Original Length X Change in temperture
Term
 Thermal Expansion (Cubical)
Definition
 Change in Volume =Cubical expansivity X Original volume X Change in temperture
Term
 Presure on canisters
Definition
 When a canister is heated then the molecules gain more energy meaning when they hit against the sides the energy increases
Term
 Specific Heat Capacity:The amount of heat required to raise the temperature of 1 kg mass by 1oC
Definition
 Specific heat capacity= Heat in (J)----------------------------mass X Change in temperture
Term
 Thermal Capacity: amount of heat require to raise the temperature of a substance of any mass by 1oC
Definition
 EnergyThermal Capacity = -------------------- change in tempertute
Term
