Question

please help me out fast very urgent ​

Answer 1

Explanation:

(i) Zero work is defined when force and displacement are perpendicular to one another and when force or displacement is zero. Example: The force acts in a downward direction, ... When displacement operates in the forward direction.

(ii) When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.

(iii) Negative work is performed if the displacement is opposite to the direction of the Force applied. Example: Work was done the gravity on a rocket going perpendicular upwards.

Answer 2

Answer:

(i)Zero work is defined when force and displacement are perpendicular to one another and when force or displacement is zero. Example: The force acts in a downward direction, ... If you push a wall, it doesn't move there's no work done.
