VECTORS A TYPE OF MEASUREMENT

A measurement with only magnitude ie: mass, distance, temperature, Scalar Quantities A measurement with only magnitude ie: mass, distance, temperature, volume, speed Distance: the total length of a path traveled Speed: distance traveled over a time interval

magnitude and direction ie: displacement, velocity, acceleration Vector Quantities A measurement with magnitude and direction ie: displacement, velocity, acceleration Displacement: distance from point A to point B, straight line, in a direction Velocity: speed with direction Acceleration: the rate at which velocity changes over a time interval, speed or direction

How A Vector Is Shown An Arrow! Magnitude is shown by the length of the arrow: 1m 5m The way the arrow is pointing indicates the direction: E NE

Vector Translation Vectors can be moved and remain the same vector so long as direction and magnitude remain constant

Vector Addition When two or more vectors are combined, their sum is called the RESULTANT

The addition of multiple vectors always sum to the same resultant Vector Paths The addition of multiple vectors always sum to the same resultant

Translate the vectors so that they form a parallelogram. Parallelogram Rule Translate the vectors so that they form a parallelogram.

Vector Components Every vector at an angle is made out of two component vectors that were added together. The components are on the X and Y axises.

Components are found using the angle and the original vector. Vector Components Components are found using the angle and the original vector. Ax = AcosΘ Ay = Asin Θ
