Unformatted text preview: requires a smaller force to generate the same angular acceleration. 4. The data graphs would have a smaller slope and an unchanged intercept. 5. The angular acceleration would increase, meaning the slope of the angular velocity versus time graph would increase. 6. The fluid from the inside of the raw egg exerts a torque on the egg, but the hardboiled egg doesn’t have that torque. This is why the raw egg will start spinning again....
