Vectors |
Numbers that have magnitude and direction (displacement, velocity, acceleration and force) |
|
|
Scalars |
Numbers that only have a magnitude associated with them (speed, distance, energy, pressure and mass) |
|
|
Vector addition |
Sum of two or more vectors is a resultant To find the sum of two or more vectors place them tip to tail To find vector components use trig X component = Vcosθ Y component = Vsin θ If X and Y are known V can be calculated using the Pythagorean theorem |
|
|
Displacement |
change in position in space does not account for pathway taken between initial and final position |
|
|
Distance |
Scalar quantity that considers the pathway taken |
|
|
Velocity |
Vector quantity measures rate of change of displacement over time and is necessarily the same direction as the displacement vector |
