Derivation of Conservation of momentum

Change of energy in a system equation(base of all dynamics)

Change in energy in a system = sum of all energy transfered in or out of the system

Net Work(some kind of energy eq)

Net Work = net change in kinetic energy

Work by friction = change in mech energy → true when?

no work removed or added to a system by a force

conversation of mech energy valid when?

Work by force applied = 0. No work by nonconservative force(friction)

Conservative force = ?

conservative force = - dU/dx

derivation of angular momentum

center of mass of rigid object with shape

r_cm = 1/m_total \int {r dm}

Parallel Axis theorem

inertia of object rotatin not around center of mass

I = I_(center of mass) + ML² (L is distance axis to cm)

object in SHP equation

d²x/dt² + w²x = 0 (x = pos of object, w = angular frequency, x can also be theta)

v_max and a_max of SHP

v_max = Aw | a_max = aw² (w = angular frequency, A = amplitude of motion.)

v_cm and a_cm from x_cm

derive once for v and twice for a over time

derivation of terminal velocity of object falling near surface of a planet.

v_terminal = sqrt(2mg/DpA) (p = density of fluid object is going through, the area the flow of the object motion goes through, drag coefficient)

Derivation Binding energy of an object to a planet(or any 2 objects to each other)

W_(F_a) = GMm/R

Derivatioin Escape velocity of an object from a planet

sqrt(2Gm/R)

Derivation Total Mechanical Energy of Orbital Object:

ME_total = − GM*m/2r

Derivation Kepler’s third law

T² = r³ (4pi²)/(Gm) (T = period, m = mass of planet, r = orbit of planet)

the equation of x in SHP to differentiate to get v and a

x = Acos(ωt + φ)

Derivation of Moment of Inertia

1. uniform ring or cylinder shell on cylinder axis

2. uniform rod at center

3. uniform cylinder or disk at cylinder axis

1. I = mR²

2. 1/12 mL²

3. ½ mR²

Quantization of charge

Q = ne (n = charge carriers, e = elementary charge)This principle states that electric charge is quantized, meaning it exists in discrete amounts represented by integer multiples of the elementary charge.

electric field around a point charge(derivation too)

E = F/q & F = kq1q2/r² → E = kq/r²

Electric field around a continuous charge distribution(derivation)

E(point charge) = kq/r² → dE = k dq/r² →(int both sides) E(condchdis) = k ∫(dq/r²)

Equation for electric flux for a flat surface in a uniform electric field

E * A → EAcos\theta

The electric potential difference across a uniform electric field. Remember d is the straight-line distance parallel to the electric field.

Motional emf(how to derive and what the eq assumes)

emf = vBL (L = length of conductor)

inductance of ideal solenoid(derivation and what its determined by)

The angular frequency of LC circuits, and therefore, all the simple harmonic motion equations for LC circuits.
