... So if we look at Newton’s Second Law, τnet = Iα or α = τnet/I, for a given torque the acceleration will be less for the second scenario because I is bigger. It would be tougher to get the second dumbbell to rotate because of where we’ve put the axis of rotation, though we haven’t actually changed th ...

Rotational Kinetic Energy
... Torque: a qualitative description The quantity torque is that which causes a rigid body to have a rotational acceleration about some axis. In order to give a rigid body a rotational acceleration, it is clear that one has to exert a force. However, where the force is applied makes a difference. If ap ...
