10 cards from this deck
Vector quantities (have magnitude and direction)
p=mv\mathbf{p} = m\mathbf{v}p=mv
J=FΔt\mathbf{J} = \mathbf{F}\Delta tJ=FΔt
J=mvfinal−mvinitial\mathbf{J} = m\mathbf{v}_\text{final} - m\mathbf{v}_\text{initial}J=mvfinal−mvinitial
Angle between initial and final velocity vectors
cosθ=u⋅v∣u∣∣v∣\cos\theta = \frac{\mathbf{u} \cdot \mathbf{v}}{|\mathbf{u}||\mathbf{v}|}cosθ=∣u∣∣v∣u⋅v
Dot product
Component-wise
Always positive (non-negative)
mvfinal=mvinitial+Jm\mathbf{v}_\text{final} = m\mathbf{v}_\text{initial} + \mathbf{J}mvfinal=mvinitial+J
