In a sitution the constant force by a rough
WebThere are different types of friction—kinetic and static. Kinetic friction acts on an object in relative motion, while static friction acts on an object or system at rest relative to each … WebConstant motion refers to any type of motion when either the distance traveled by the object is the same for each second, or the speed of the object changes by the same amount …
