Work-Energy Principle (Edexcel A-Level Further Mathematics): Flashcards

Change in kinetic energy

$W = Fd\cos\theta$

$W = Fd$

$W = 0$

$W_\text{net} = \Delta KE = KE_\text{final} - KE_\text{initial}$

$KE = \frac{1}{2}mv^2$

Change in kinetic energy

$F = mg\sin\theta$

$W = mg\sin\theta \cdot d$

Angle between force and displacement
