Which component is responsible
Only horizontal part (Fx)
If the angle were increased, how would it change the size of the:
Vertical component? Increase
Horizontal component?
Decrease

Ex 1) A car is pulled with a force of 60. N at angle of 37° from the horizontal. Find the vertical and horizontal components of the applied force
Using Trigonometry
F_{y} = 60. Nsin37°
F_{y} = 36 N Up
F_{x} = 60. Ncos37°
F_{x} = 48 N Right
Check a^{2 }+ b^{2} = c^{2}
36 N^{2} + 48 N^{2}= 60. N^{2}
Ex 2) Weight of Cart = 80 N
Horizontal Component
O N
Vertical Component
80. N
Horizontal Component 0 N
Vertical Component 80 N down
Ex 3) A 50. N force at an angle of 80° has its' angle changed to 10.°.
How will the vertical and horizontal components change?
Vertical component  smaller
Ex 4) Parallel & perpendicular components
F = 10. N (Weight)
F = 10. N (Weight)
Find the force holding cart on ramp and force that acts down
Force (down
ramp) = F_{applied
