Forces (Junior Cert Science): Flashcards

Speed up, slow down, or change direction (accelerate)

Newton (N)

Equal in size, opposite in direction

Cause objects to accelerate (change velocity)

Opposes motion between surfaces

Amount of matter in object; measured in kg

Force of gravity on body; measured in N

$w = m \times g$

$10 \text{ m/s}^2$

Extension is directly proportional to applied force
