Physics GCSE Notes
Forces and Motion
Movement and Position
Distance-time and veolocty-time graphs
D-T graphs
Gradient= steady speed
Flat = stopped
Flat= going back towards starting point
Curves= acceleration/ deacceleration
Calcualting speed from a distance time graph is just the gradient
speed = gradient = vertical/ horizontal
V-T graphs
Flat line = steady speed
Gradient= acceleration
Steaper line = greater acceleration
Uphill sections = acceleraction
Downhill sections = deacceleration
Cure = change in acceleration
Equations
Speed= distance / time
acceleration = change in veolocity/ time
Forces, movement and momentum
Forces and friction
Forces
Gravity/ weight- pulls some thing streight down
Astronomy
Magnitism And Electromagnitism
Energy
Waves
Electrisity
Radiactivity
