H2 Physics 3 - Motion and Forces: Object on an Inclined Plane

What you will learn

• 5 kg block on a smooth 30 degree incline released from rest; goal is acceleration down the plane and the normal reaction.
• Resolve weight: mg sin theta down the slope and mg cos theta perpendicular; W = 49.05 N.
• Along the plane only mg sin theta acts, so a = g sin theta = 9.81 x 0.5 = 4.91 m/s^2 down the slope.
