Question

Work done by kinetic friction is always negative

Answer 1

Answer:

Please make me a brainlist answer and like and follow please

Explanation:

Answer ⇒ Yes, work done by the kinetic friction on the object can be positive and also zero. Work done by the kinetic friction on an object is always the negative because the displacement is always opposite to the the frictional force.

Answer 2

Friction is defined as the resisting force on a solid surface, or fluid layers, from sliding against each other.

Explanation:

• There are different types of friction, one among which is the kinetic friction. Kinetic friction is also known as sliding friction. This friction occurs when two moving objects are in motion relative to one another and rub together.
• At a given time of interaction between two surfaces, static friction does no work. in the same time frame, kinetic friction always occurs in the direction opposite to the motion occurring.
