Lab 3: g from ball rolling down a ramp

All parts of the lab are required

Purpose: Verify that the acceleration due to gravity is 9.8 m/s^2. There will be some errors due to the moment of inertia of the ball rolling, which we will cover later in the course.

Data:

Time (s), Height (m), Length (m), Vavg (m/s), V_f(m/s), Vf²/2 ( (m/s)^2), sin q,a (m/s^2),

Graph: a vs sin q. You must pick which distance Dx represents and justify your choice in the conclusion.

Equations used in calculations:

V_avg = Dx/Dt

V_f= 2V_avg

Vf²/2 (y-axis)

sin q = h/L

a =(Vf²/2)/Dx

Conclusion: Include the experimental value for the acceleration due to gravity (g), sources of errors in the lab procedure, and why you picked either height or length for Dx.

I need help

Data values could be accurate or not
