GEN PHYSICS FINALS

describes magnitude and direction

• Vector

• Scalar

describes magnitude only

• Vector

• Scalar

4 Major Directions

• North, South, East, West

• Up, Down, Left, Right

• Front, Back, Side

x:_____ ; y:_____

• horizontal; vertical

• vertical; horizontal

change in position of an object; states how far object moves and its direction

• Displacement

• Magnitude

• Direction

angle of rotation of vector about its "tail" from north, south, east, and west

• Displacement

• Magnitude

• Direction

length of vector; m, mm, cm, km

• Displacement

• Magnitude

• Direction

C = A + B; A followed by B results the same as if the particle had started at some initial point and undergone a single C

WAYS TO GET THE RESULTS IN VECTOR ADDITION

• adding in reverse order

• head-to-tail method

• adding by constructing a parallelogram

• add then square

TYPES OF SUM OF VECTORS

• parallel vectors

• antiparallel vectors

• linear vectors

• intersecting vectors
