Question

State the condition for positive, negative and zero work done.​

Answer 1

Answer:

Positive work: when force and displacement are in the same direction, the work performed on an object is said to be positive work. ... Zero work: When force and displacement are perpendicular to each other, or when force or displacement is zero.

Answer 2

Answer:

POSITIVE, NEGATIVE , ZERO

Explanation:

1.POSITIVITE = if the displacement of the body is in the direction of the force then work done is positive.

2.NEGATIVE = if the displacement of the body is in opposite direction of the force then work is negative.

3.ZERO = zero work is done when displacement of the body is zero or perpendicular to to the direction of force applied then work done is zero.
