WebMay 28, 2024 · When work is done we know because there is? You know that work is done if the following two conditions are met: The object moves as a force is applied. The direction of the object's motion is the same as the direction of the force applied. Why do things move? Force can make things move, change shape or change their speed. WebAnswer (1 of 9): Yes, it does is possible with respect to a moving body or accelerated observer, the body observed seems to be in motion. The motion cant be without force unless body was moving or it is a non inertial frame.
