The acceleration of a block on an incline in the absence of friction is related to the angle of the incline by the equation, a = gsinθ where θ is the incline angle and g is the acceleration due to gravity. Assuming this equation is correct, use your measured acceleration to determine the value of g? Recall that you used a 4 cm block under one end of a 1.2 meter long track. How does your value compare to the actual value of g = 9.8 m/s2?
