Resource summary

Question Answer
vector quantity with both magnitude and direction
scalar quantity with only magnitude
tail starting point of vector
head final pointed end of arrow
resultant sum of two or more vectors
horizontal component -component of vector A along x-axis -A_x = Acosθ
vertical component -component of vector A along y-axis -A_y = Asinθ
magnitude of resultant A = √(A_x)^2 + (A_y)^2 )
direction of resultant θ = tan^-1(A_y/A_x)
projectile motion motion of object thrown into air; subject to only acceleration of gravity
components of velocity -v_x = vcosθ -v_y - vsinθ
horizontal motion of projectile -x = x_0 + v_x t -v_x = v_x0
vertical motion of projectile -y = y_0 + 1/2 (v_0y + v_y) t -v_y = v_0y - gt -y = y_0 + v_0y t - 1/2 g t^2 v_y^2 = v_0y^2 - 2g (y - y_0)
maximum height of projectile h = (v_0y^2)/2g
range -horizontal distance traveled by projectile -R = [v_0^2 * sin(2θ)]/g
relative velocity formula v_ac = v_ab + v_bc
