- 1Equation for SpeedSpeed = distance/time
- 2Unit for speed, distance and time equationspeed- m/s distance-, time-s
- 3Equation for Accelerationacceleration= change in velocity/time taken. A=v-u/t
- 4Newton's second law and equationForce= mass x acceleration. Force is proportional to acceleration and acceleration is inversely proportional to 1/m.
- 5units for force, mass and accelerationNewtons (F), Kilograms (M), m/s*2 (A)
- 6Equation for WeightWeight = Mass x gravitational field
W= mg - 7Law of conservation of momentumMomentum before= momentum after
- 8Momentum equationMomentum= Mass x Velocity
kg m/s - 9Equation linking Force and momentumForce = Change in Momentum/Time Taken
- 10Hooke's LawThe Force is proportional to the Extension
F= spring constant x extension - 11Equation for Stopping DistanceStopping Distance= Thinking Distance + Braking Distance
- 12Law of momentsSum of anticlockwise moments= Sum of clockwise moments
- 13Equation linking moments, distance and forceMoment (Nm)= Force x Perpendicular Distance from the pivot
- 14Orbital Speed=?Orbital Speed= 2x Pi x Orbital Radius/ Time
- 15Equation for Power?Power = Current x Voltage
P=IV - 16Energy Transferred= ?Energy Transferred= Current x Voltage x Time
E= I x V x T
Elvis Is Very Talented - 17Voltage equationVoltage = Current x Resistance
V=IR
Very Important Rule - 18Charge= ?Charge= Current x Time
Q=IT - 19Wavespeed equation?Wavespeed= Wavelength x Frequency
- 20Frequency equationFrequency = 1/time period
- 21Law of ReflectionAngle of incidence= Angle of Reflection
- 22Equation for Refractive indexRefractive index= Sin(incident angle)/ Sin(Reflected angle)
n=Sin(i)/Sin(r) - 23Equation for Critical angleSin(C)= 1/n
n being the refractive index - 24Equation for densityDensity = Mass/Volume
P (row) = M/V
g/cm*3 or Kg/m*3, Kg or g and m or cm - 25Equation for Pressure, Symbols and UnitsPressure = Force/Area
p=F/A
Pascals (newtons per metre squared), Newtons, Metres squared - 26Equation for pressure differencePressure difference= Height x density x gravitational field strength,
P= h x p x g
Pascals= M x kg/m*3 x N/kg - 27Boyle's LawP1 x V1 = P2 x V2
P= Pressure, V= Volume
P= N/m2 or pascals, V= m*3 - 28Other gas law on temperature and pressure.p1/T1 = p2/T2
Remember The T has to be in KELVIN!! - 29Energy Efficiency EquationEnergy Efficiency = Useful Energy Output/ Total Energy Input
- 30Work Done EquationWork Done= Force x Distance Travelled
Joules, Newtons, Metres - 31Power =?Power = Work Done/Time Taken
Watts, Joules, Seconds - 32Kinetic Energy EquationKE= 0.5 x Mass x Velocity*2
KE= 1/2MV*2
Joules, Kilograms, m/s - 33Gravitational Potential Energy (GPE) equationGPE= Mass x Height x Gravitational Field Strength
Joules, Kilograms, Metres, N/Kg
