1Force is reperesented in diagrams by a straight line with an arrow to show its direcion of action.
- AVerdadero
- BFalso
2Usually more than one force acts on an object.
- AVerdadero
- BFalso
3If an object is at rest, the forces must balance.
- AVerdadero
- BFalso
4The [blank_start]resultant[blank_end] of forces acting in the [blank_start]same[blank_end] straight line is found by addition or [blank_start]subtraction[blank_end].
- Aresultant
- Bsame
- Csubtraction
5If two [blank_start]forces[blank_end] acting at a [blank_start]point[blank_end] are represented in [blank_start]size[blank_end] and [blank_start]direction[blank_end] by the sides of a [blank_start]parallelogram[blank_end] drawn from the point, their [blank_start]resultant[blank_end] is represented in size and direction by the [blank_start]diagonal[blank_end] of the parallelogram [blank_start]drawn[blank_end] from the point.
- Aforces
- Bpoint
- Csize
- Ddirection
- Eparallelogram
- Fresultant
- Gdiagonal
- Hdrawn
6Scalars are added by ordinarny arithmetic, while vectors are added geomtrically.
- AVerdadero
- BFalso
7The [blank_start]maximum[blank_end] value of friction is called starting or [blank_start]static[blank_end] friction.
- Amaximum
- Bstatic
8When friction is [blank_start]less[blank_end] than its [blank_start]maximum[blank_end] value, it is called sliding or [blank_start]dynamic[blank_end] friction.
- Aless
- Bmaximum
- Cdynamic
