Here are all the formulas I have learned in my pre-AP physics class so far, I just finished the 1st semester:(adsbygoogle = window.adsbygoogle || []).push({});

They are in no particular order.

[tex]F_c = \frac {mv^2}{r}[/tex]

[tex]a_c = \frac {v^2}{r}[/tex]

[tex]F_F = \mu * F_N[/tex]

[tex]C = 2 * \pi * r[/tex]

[tex]V_f = V_i + at[/tex]

[tex]V_f^2 = V_i^2 + 2ad[/tex]

[tex]d = V_i * t + \frac {1}{2} * at^2[/tex]

[tex]d = \frac {1}{2} (V_f + V_i) * t[/tex]

[tex]v = \frac {d}{t}[/tex]

[tex]F = ma[/tex]

[tex]F = \frac {G * m_1 * m_2}{r^2}[/tex]

[tex]g = \mu * a[/tex]

[tex]g = \frac {Gm}{r^2}[/tex]

[tex]v_o = \sqrt {\frac {Gm}{r}}[/tex]

[tex]P.E. = mgh[/tex]

[tex]W = Fd[/tex]

[tex]K.E. = \frac {1}{2} * mv^2[/tex]

KEY

[tex]F_c[/tex] = centripital force

[tex]a_c[/tex] = centripital acceleration

m = mass

v = velocity

r = radius

[tex]F_F[/tex] = frictional force

[tex]F_N[/tex] = normal force(weight)

[tex]\mu[/tex] = coefficient of friction

C = circumference

[tex]V_f[/tex] = final velocity

[tex]V_i[/tex] = initial velocity

a = acceleration

d = distance

g = acceleration due to gravity

t = time

G = gravitational constant

P.E. = potential energy

K.E. = kinetic energy

W = work

some important values:

mass of the earth = [tex]5.98 * 10^24 kg[/tex]

radius of the earth = [tex]6.38 * 10^6 km[/tex]

radius of the moon = [tex]1.74 * 10^3 km[/tex]

mass of the moon = [tex]7.35 * 10^35 kg[/tex]

gravitational constant = [tex]6.67 * 10^-11 \frac {N*m^2}{kg^2}[/tex]

Feel free to add anything or make suggestions. I will add more as the year goes on. I hope this helps some of you.
