NEWTON'S LAWS
OF MOTION
First Law: rest and motion
Second Law: Force, mass, acceleration
Third Law: Action and reaction
First Law: Rest and Motion
Second Law: F = m · a
Second Law: Not this...
Third Law: Action and Reaction
REFERENCE SYSTEM
GRAVITY: F = G·M·m / r²
GRAVITY:
Simplification: F = m·g
FRICTION (I) : Static and Dynamic
Dynamic : F = k · v
· Static : Fmax = k · N
FRICTION (II): Aerodynamic
IMPULSE (I): (not this)
IMPULSE (II): This
ELASTICITY CONSTANT: F = K · x
ANGULAR MOMENTUM: L = r · m · v
Turning, Axis
COLLISIONS: Elastic, Inelastic
All togheter...
