Force acts in 2 directions

 

 

Drawing Components

St. Mary's HS Physics

 

 

 

 

 

 

 

 

 

 

Which component is responsible for making this cart move? 

 

 

 

 

Only horizontal part (Fx)
of applied force

 

#18 - Angle and components

 

If angle were increased....

 

Vertical component?    

Increase

 

 

Horizontal component?

 

 

Decrease

 

 

Fy = FsinӨ

 

Fx = FcosӨ

 

"One size fits all"

 

 

 

 

 

 

Fy = 60. Nsin37

 

 

Fy = 36 N North

 

 

Fx = 60Ncos37

 

 

Fx = 48 N East

 

 

 

Check  a2 + b2 = c2

 

  

36 N2 + 48 N2= 60 N2

 

 

Ex) Weight of Cart = 80 N

 

 

Horizontal Component of Weight Force?

 

 

 

 

O N 

 

Vertical Component of Weight Force?

 

 

 

8O N

 

  

 

Horizontal Component

 0 N

 

Vertical Component

80 N down

 

 

Ex) A 50 N changes from 80 to 10. 

 

vertical component?

 

 

decreases

 


Angle & Components

St. Mary's HS

 

Ex) A 50 N changes from 80 to 10. 

 

horizontal component?

 

 

increases
