Finding how vectors change with respect to time
Differentiate each component separately
Velocity vector vˉ\bar{v}vˉ
Acceleration vector aˉ\bar{a}aˉ
Magnitude of the velocity vector
a2+b2\sqrt{a^2 + b^2}a2+b2
Speed is magnitude only; velocity includes direction
Identify, Differentiate i, Differentiate j, Combine
After differentiating, not before
m (metres)
m/s
m/s²
Always positive (it's a magnitude)
