FORMULA CHART for Grades 10-11 Science Assessment
Density = mass volume = D= m v
heat gained or lost by water
Speed = distance time
mass in grams
change in temperature
specific heat
Q = (m)(T)(Cp) s= a= p= d t v f -v i t mv
Acceleration =
final velocity – initial velocity change in time
Momentum = mass x velocity Power = work time work output work input x 100
W P= t WO % = WI KE = x 100
% efficiency =
Kinetic energy =
1 (mass x velocity2 ) 2
mv 2 2
Gravitational potential energy = mass x acceleration due to gravity x height Energy = mass x (speed of light) 2 Velocity of a wave = frequency x wavelength Current = voltage resistance
GPE =mgh E = mc 2 v = f I= V R
Electrical power = voltage x current Electrical energy = power x time Mechanical advantage = force out force in
P = VI E = Pt Fo MA = Fi
Constants/Conversions g = acceleration due to gravity = 9.8 m/s 2 c = speed of light = 3 x 10 8 m/s speed of sound = 343 m/s at 20 C 1 cm 3 = 1 mL 1 wave/second = 1 hertz (Hz) 1 calorie (cal) = 4.18 joules 1000 calories (cal) = 1 Calorie (Cal) = 1 kilocalorie (kcal) Newton (N) = kg m/s 2 joule (J) = Nm watt (W) = J/s = Nm/s volt (V) ampere (A) ohm ()
