Question

when will the work done is positive?​

Answer 1

Answer:

when force and displacement are in the same direction , the work performed on an object

Answer 2

When the force and displacement are in same direction, work done will be positive.

Explanation:

Formula of Work done by a body ↓

W = Fd cosθ

• F → force
• d → displacement
• θ → angle between force and displacement

REASON :-

• If the force and displacement are in same direction.
• Then, angle between them will be 0 degrees.
• So, work done is F × d i.e. positive work.

Hence, when the force and displacement are in same direction, work done will be positive.
