resolving vectors Flashcards
(7 cards)
if an object is moving at a steady speed, what can be said about the forces acting upon it?
they must be balanced as only an unbalanced force can change the motion of an object
resultant vectors acting at an angle can be resolved into what two components?
horizontal and vertical
on a scale drawing, components should be described with both. . .
magnitude and direction
state the definition of a component
a single horizontal or vertical vector
how do you calculate the resultant vector if they are acting in the same direction?
add them together
how do you calculate the resultant vector if they are acting in opposite directions?
subtract them from each other
when you have measured your resultant vector length with a ruler how do you convert it to the real magnitude?
scale multiplied by length
