Chapter 6 Equilibrium Flashcards
what is a vector
A vector is a physical quantity that has a direction as well as a magnitude.
what is a scalar
A scalar is any physical quantity that is not directional.
Displacement
distance given in a given direction.
velocity
is the sped in a given direction.
Force and acceleration
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.
moment = what ?
moment = force x perpendicular distance from the line of the action of the force to the pivot.
