Two people sit on two ends of a seesaw. They sit in positions such that the seesaw is balanced in a horizontal position. When one person leans toward the center of the seesaw, that person's end of the seesaw will fall, rise, or stay at the same level.
If the net torque on an object is zero, its angular speed or angular acceleration is zero.
About which axis will the moment of inertia of a person be smallest? vertical axis that passes from head to toe horizontal axis that passes through the stomach and spinal cord
In your own words, explain what moment of inertia is. I don't want equations. I just want a short conceptual explanation. It is the resistance of an object to change in its angular velocity. This is analogous to the definition of mass (inertia) which is the resistance of an object to change in its velocity.
