Alevel Physics/Forces, Fields and Energy/Appendix of Formulae
Formulae by Section[edit]
This is the list of required formulae in the order that they appear in the OCR Syllabus for this module.
Dynamics  
Momentum is mass times velocity.  
Force is the rate of change of momentum with respect to time.  
Work and Energy  
Work is force times displacement  
Kinetic energy is half of mass times velocity squared.  
Potential energy is mass times acceleration due to gravity times height. (For situations near the surface of the earth only)  
Circular Motion  
Centripetal acceleration is velocity squared divided by the radius.  
Centripetal force is mass times velocity squared divided by the radius. (You are expected to be able to derive this from and ).  
Oscillations  
Period is one over the frequency.  
Acceleration is proportional to the negative displacement from the centre of oscillation.  
Displacement from the centre of oscillation is amplitude times position in cycle. (When oscillation started at centre).  
Displacement from the centre of oscillation is amplitude times position in cycle. (When oscillation started at one end).  
Angular Velocity is 2 times over the time period.  
Angular Velocity is 2 times times the frequency of oscillations.  
Gravitational Fields  
Force is Gravitational Force Constant () times mass one times mass two over radius squared.
