Question

Equation 5 : In part A of this lab, we will plot the torque due to the string versus angular acceleration (Ts vs. a). According to equation 5 in the lab manual, the data should be well fit by a straight line. 4. What are the (SI) units of the slope of the plot (r, vs. o)? 5. What should the slope of the plot be equal to? 6. What are the (SI) units of the y-intercept of the plot? 7. What should the y-intercept of the plot be equal to? 8. Would you expect the y-intercept to be positive, negative or zero?

Explanation / Answer

equation 5 is similar to y = m*x + c

m-------is the slope

4) the SI unit of slope is kg-m^2

5) the slope is equa to T / alpha that is the

equal to moment of inertia

6) The Si unit of y-intercept is N-m ( for torque)

7) The y - intercept should be equal to net torque

8) The torque is positive [ A straight line in first quadrant ]
