Answer 1

Answer:

ur siso is here❣️☺️

Explanation:

text

L = r × p

L = r × mv

L = mr × (ω × r)

L = mω(r · r) − mr(r · ω)

L = mr2ω − 0

L = mr2ω

L = Iω

Moment of inertia again

I = ∑r2m = ⌠

⌡ r2 dm = ρ ⌠

⌡ r2 dV

Conservation of angular momentum

∑τ = d L = 0

dt

Thus

L = constant

Translational and rotational quantities compared

concept translation connection rotation

momentum p =

mv L = r × p = mr × v L = Iω

impulse-momentum ∫ F · dt

F =

= ∆p

dp/dt

∫ τ · dt
