physics chapter 3 test review

vector

quantity with both direction and magnitude

vector quantities

displacement, velocity, acceleration, force

scalar

quantities that have magnitude and but not direction

scalar quantities

time, speed, # of something, volume

resultant

sum of two or more vectors

equilibrant

single vector that produces equilibrium

horizontal motion

constant vx, no aire resistance

vertical motion

combination of motions, accelerated motion due to gravity

trajectory

the path followed by a projectile (parabola)

projectile

objects given in an initial horizontal velocity then only accelerated by gravity

range

horizontal distance from launcher until projectile returns to surface height.

motion

described in terms of position, velocity, and acceleration
