👉 In physics, a backstroking object is an object that moves backward in the direction of the force applied to it. This can be seen as a special case of a sliding motion where the object slides along a surface without slipping and with no friction between the object and the surface. A backstroking object has an acceleration (a) opposite to the direction of the force (F), which means that its velocity changes in the opposite direction of F. This is because the object is moving backward,
