Chapter 6 Equilibrium Flashcards
1
Q
what is a vector
A
A vector is a physical quantity that has a direction as well as a magnitude.
2
Q
what is a scalar
A
A scalar is any physical quantity that is not directional.
3
Q
Displacement
A
distance given in a given direction.
4
Q
velocity
A
is the sped in a given direction.
5
Q
Force and acceleration
A
are both vector quantities and therefore can each be represented by an arrow in the appropriate direction and of length in proportion to the magnitude of the quantity.
6
Q
moment = what ?
A
moment = force x perpendicular distance from the line of the action of the force to the pivot.
