Two-Dimensional Motion

Inclined Planes

Inclined Planes

A simple block on an incline

30°

Fg


Inclined planes1
Inclined Planes

B/c the block in on an incline,

we adjust our coordinate system to fit the incline

Y

X

30°

Fg

Aligning the X axis with the Incline


Inclined planes2
Inclined Planes

  • Notice the gravitational force (Fg) is pulling straight down

  • Doesn’ t the Fg also pull you down the hill?

    YEP!

    So, there are components of the Fg

    (x and y)

  • There is an Fgx and an Fgy

  • Notice that the coordinate system has been adjusted… How much?

Y

X

30°

Fg

It has been adjusted by the incline, 30°

  • Therefore the angle between Fg and Fgy is…

    30°

  • Therefore the angle between Fg and Fgy is…

  • Now we are able to solve for fgx and fgy

  • Fgx is the force pulling the block down the incline

  • Fgy is the force keeping the block in contact with the incline

  • Realign the vectors (Tip-to-Tail) to complete a right triangle and you get…

Inclined plane problem
Inclined Plane Problem

  • A 784-N skier on a hill that makes a 35 angle with the horizontal begins to accelerate down the hill.

    • Draw the pictorial diagram and free-body diagram

    • What is the component of the skier’s weight parallel to the incline plane?

    • What is the normal force?
