A block is sliding down the rough plane, the work done by the frictional force is
Answers
Answer:
work done by the frictional force is opposite to the direction of motion in which the body is sliding down
Answer:
The work done by the frictional force will be opposite to the direction of that of the motion.
Explanation:
The force of friction acts in the direction counter to the direction of motion when a body is sliding over a rough horizontal surface. As a result, displacement and force are in opposing directions. As a result, the work produced by a body moving on a rough surface due to friction is negative. Because friction is a response force brought on by the irregularities on the surfaces in contact, it always works in the opposite direction to the direction in which the body is moving. This means that friction opposes the motion between two surfaces in order to keep the body at rest.
Thus, when a force works in the opposite direction to the motion of an item, the work done is negative. Various forces acting on bodies of different masses do the same amount of work.
