Torque is defined as a moment that causes rotational motion in objects, and it is influenced by the point of force application relative to the center of mass. When a force of 10N is applied to a 10kg block away from its center of mass, the block does not necessarily experience linear acceleration less than 1m/s². The discussion raises questions about whether pushing a block at its center of mass requires the same energy as pushing it elsewhere, highlighting that more work is done if the same force is applied over a greater distance. The concept of "harder to push" is subjective and requires clarification. Understanding these principles is crucial for analyzing motion and energy in physics.
