∑Fx=Rx y ∑Fy=Ry
- R=√(Rx)^2+(Ry)^2
- Newton's First Law
Anmerkungen:
- An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
- Conditions ∑F=0 => Equilibrium
Anmerkungen:
- free particle: not subject to any interaction
- Rest
Anmerkungen:
- Constant motion
Anmerkungen:
- Newton's Second Law
Anmerkungen:
- Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
- ∑F=m*a
Anmerkungen:
- Newton's Third Law
Anmerkungen:
- For every action, there is an equal and opposite reaction.
- F a->b = - Fb->a
- acts on different bodies
