Question

differentiate between positive work negative work and zero work​

Answer 1

Hello❤

• When force and displacement both are in same direction, the work done is said to be positive.
• When force and displacement are in opposite directions, the work done is said to be negative.
• And, work done is said to be zero when force or displacement are perpendicular to each other. Or, either of them is zero.

Thank you ❤

Answer 2

Explanation:

Positive work - when the force and displacement are in same direction the work is called positive work.

Negative work- when the force and displacement are in opposite directions the work is called Negative work.

Zero work- When the applied force does not cause any displacement then it is Zero work.
