Question

an object on a floor is dragged, it is displaced in the direction of force applied. What is the force that causes negative work, when it is dragged through the floor​

Answer 1

Answer:

Force applied in the opposite direction and the work done by the friction in opposite direction of the object displaced

is an example of negative work done.

Answer 2

While an object is dragged on the floor and gets displaced in the direction of force applied, the frictional force is responsible for the negative work.

Explanation:

• The friction force is a type of force that resists the motion when one object comes in contact with another object.
• The scenario given in the question is about sliding friction.
• The work done by the frictional force is negative because it always opposes the relative motion.
