Physics - Motion Equations and Definitions

Equations regarding momentum and other stuff that aren't in the data booklet

horizontal velocity (projectile motion)

ucosθ

vertical velocity (projectile motion)

usinθ

collisions - stick together

M₁V₁ = (M₁+M₂)V’

collisions - drift apart

M₁V₁ + M₂V₂ = (M₁+M₂)V’

explosions definition

equal momentum but opposite direction (P₁=-P₂)

law of conservation of momentum

in an isolated system, total momentum is constant

explosions - bounce apart

-M₁V₁’ = M₂V₂’

terminal velocity

2πr²g(Ps-Pf)/9πη

two characteristics of an ideal fluid

streamlined flow, incompressible
