a. occurs when a freely movable object moves in a rectilinear or curvilinear path regardless of where the force is applied
b. occurs when a freely movable object moves in a straight line regardless of where the force is applied
c. occurs when distractive force is applied to the center of an object
d. occurs when an object is free to move only in a rotary path regardless of where force is applied
Answer: d. occurs when an object is free to move only in a rotary path regardless of where force is applied
Rotary motion occurs when an object is free to move only in a rotary path regardless of where force is applied. Rotary motion can also occur when force is applied off center to a freely moving object.
