📷 A 2 kg block on a frictionless incline (30°). Find its acceleration.

📖 Concept first

1 On a frictionless incline, only gravity's component along the slope pulls the block down. That single component sets the acceleration.

2 The pulling force is mg sin θ. Divide by mass and the mass cancels out.

a = g sin θ = 9.8 × sin30° = 4.9 m/s²
