Formulas and Constants
Speed of light constant
1/ 299 792 458 per second(in a vacuum)
Density Formula
Density = mass/volume
𝙋 = M/V
Speed Formula
Speed = distance/time
s = d/t
Average Speed Formula
Average speed = total distance/total time
a.s = t.d/t.t
, Time Formula
Time = distance/speed
t = d/s
Distance formula
Distance = area under speed - time graph
d = a.u.s - t.g
Area of Triangle Formula
Area = ½ * base * height
a = ½ bh
Alternate Speed Formula
Speed = gradient of distance - time graph
s = g.o.d - t
Acceleration formula
acceleration = change in velocity/time taken
a = (v-u) / t
Alternate Acceleration Formula
acceleration = gradient of speed - time graph
A = g.o.d - t
Acceleration of Free fall constant
g = 10 m/s 2
Weight Formula
Weight = mass * acceleration of free fall
W = mg
Force Formula
Force = mass * acceleration
F = ma
