TRUE or FALSE: the work done by a force is always perpendicular to the direction of the motion?

TRUE or FALSE: the work done by a force is always perpendicular to the direction of the motion?





Can You AnswerTRUE or FALSE: the work done by a force is always perpendicular to the direction of the motion?
False : More often than not the work done by a force is parallel or directed at an angle where only a portion of the force is translated as work. The only force that is usually perpendicular to an object in motion is the force of gravity.TRUE or FALSE: the work done by a force is always perpendicular to the direction of the motion?
False, it is parallel.
False. You're probably thinking of torque or the ';moment';
Yes, I can answer.








If you want that answer, it's false. Work is the product of movement and the component of force parallel to the direction of movement. The component of force perpendicular to the direction of movement does zero work.
