Specific charge the charge to mass ratio or charge in coulombs divided by the mass in kilograms Isotope a nucleus with the same number of protons but different number of neutrons Hadron a particle that experiences the strong nuclear force. Composite particles made of either qqq (baryons) or q anti-q (baryon) Antimatter Particles with the same mass but opposite charge Photoelectric effect the emission of electrons from metal surfaces by light of an appropriate frequency Photon a discre...

Weight Mass x Gravitational Field Strength Vector A quantity with size and direction Scalor A quantity with size only Newton's 2nd Law Resultant Force = mass x acceleration Displacement Position of an object relative to an origin Average Speed Distance Travelled / Time taken Instantaneous Speed distance travelled in an instant / time duration of an instant

AQA AS Physical Chemistry Exam Questions and Answers Who described atoms as solid spheres that make up different elements and when? - Answer- John Dalton in the 19th century Who suggested that atoms of a particular element had the same mass and atoms of different elements had different masses and when? - Answer- John Dalton in 1803 Who discovered the electron and when? - Answer- JJ Thomson, 1897 discovered electrons proving atoms weren't indivisible or solid. New model named plum puddin...

Physics Waves AQA AS Exam Questions and Answers 100% Pass What does a wave do? - Answer- Transports energy from one place to another What are mechanical waves? - Answer- Mechanical waves use particles to transfer energy (neighboring particles bump into each other and set their neighbors moving) What are electromagnetic waves? - Answer- Electromagnetic waves don't use particle vibration to transfer their energy and can therefore travel through a vacuum. e.g. light What is the unit of freq...
