If the net work done on an object is zero
Web2 dagen geleden · Positive Work - When we apply force on an object in its direction of motion. Negative Work- Force applied in the opposite direction. Zero Work - When the force is applied in a direction perpendicular to the direction of the object’s motion, it is zero work done, as W = Fd Cos 90° = Fd (0) = 0 work done. WebA machine carries a 4.0 kg package from an initial position of d i=(0.50m) i^+ (0.75m) j^+(0.20m) k^ at t = 0 to a final position of d f=(7.50m) i^+(12.0m) j^+ (7.20m) k^ at t = 12 s. The constant force applied by the machine on the package is …
