Question 2

Resolving a Vector is the Opposite of…

Answer 2

Adding Vectors.

Question 3

A Single Resultant Vector Can be ___ into: (2)

Answer 3

Resolved, into:

-x-Component

-y-Component

Question 4

It is Possible to ___ Force Vectors into its ___ & ___ ___, using Trigonometry.

Answer 4

Resolve, Horizontal, Vertical, Components.

Question 5

Objects on an Inclined Plane is a Common Scenario in which Vectors Need to be Resolved. An Inclined Plane, or a Slope, is a Flat Surface that is Tilted at an…

Answer 5

Angle.

Question 6

When Considering Forces on an Inclined Plane, Instead of thinking of the Component of the Forces as Horizontal & Vertical, you Can think of them as ___ or ___ to the Slope.

Answer 6

Parallel, Perpendicular.

(bc now its no longer a horizontal surface- it is inclined at an angle)

Question 7

The Weight of the Object is ___ ___, & the Normal (or Reaction/Contact) Force is Always ___ ___ from the Object.

Answer 7

Vertically Downwards, Vertically Upwards.

Question 8

The Weight W of the Object on the Slope Can be Resolved into the Following Components: (2)

Answer 8

-Parallel to the Slope: Wsinθ

-Perpendicular to the Slope: Wcosθ

Question 9

For an Object on a Slope, If there is No Friction, which Force will Cause the Object to Move Down the Slope?

Answer 9

The Component of Weight Parallel to the Slope (Wsinθ).

Question 10

Answer 12

Closed Vector Triangles.

Question 13
