Work (VCE SSCE Physics): Flashcards

Energy transferred by a force causing movement

Scalar (has magnitude, can be +ve or -ve)

$W = Fs \cos\theta$

Joules (J)

Zero

Negative work ($\cos 180° = -1$, so $W = -Fs$)

Energy transferred to object (increases kinetic energy)

Energy removed from object (decreases kinetic energy)

Zero (no work done)

Area under the curve
