P5 Formulas
Work Done
= Force X Distance
Force on a spring
= Spring Constant X Extension
Elastic Potential Energy
= 1/2 X spring constant X extension^2
Moment of a force
= Force X Distance
Pressure
= Force / Area
Pressure in liquids
= height X density of liquid X gravitational field strength
Distance
= speed X time
Acceleration
= change in velocity / time
Final velocity^2
= initial velocity^2 + 2 X acceleration X distance
Force
= mass X acceleration
Momentum
= mass X velocity
Weight
= Mass X Gravitational Field Strength
P6/7 Formulas
Wave Speed
= Frequency X Wavelength
Angle Of Incidence
= angle of reflection
Magnification
= image height/object height
Force
= magnetic flux density X current X length of wire
