Net Force

Resultant force

1.1

Resultant force

	Resultant force
	A single force that represents the effect of combination of two or more forces by magnitude and direction.

Addition of forces (resultant force)

Parallel forces
Non-parallel forces
- Triangle method (start at different points)
- Parallelogram method ( start at the same points)
Perpendicular forces (Phytagorean Theorem)

a) Stationary @ constant velocity
\(R=mg\, cos \,\alpha\\ Fg=mg\, sin\, \alpha\)

b) Acceleration
\(mg\,sin\,\alpha-Fg=ma\)
