A research team has recently devised a novel mechanism to transport droplets at record-high velocity and distance without extra energy input, and droplets can be moved upward along a vertical surface, ...

Multiple forces act on an object at the same time. The size and direction of these forces determines the movement of the object. Show the forces acting on an object in a free body diagram. The arrows ...

Objective: The biomechanics of the head for punches to the jaw and the risk of head injury from translational and rotational acceleration were studied. Methods: Seven Olympic boxers from five weight ...
