Question

explain positive negative and zero work with example pls help me​

Answer 1

Answer:

It's super simple bro

Explanation:

Positive work: when force and displacement are in the same direction, the work performed on an object is said to be positive work. ... Example: Work was done the gravity on a rocket going perpendicular upwards. Zero work: When force and displacement are perpendicular to each other, or when force or displacement is zero.

Please mark as brainliest answer

Answer 2

Answer:

POSITIVE WORK: The work done on an object is said to be positive work when force and displacement are in same direction.

Example: When an object moves on horizontal surface, force and displacement acts in same direction. So, work done is positive.

NEGATIVE WORK: The work done is said to be negative work when force and displacement are in opposite direction.

Example: When an object is thrown upwards,the force of gravity is in downward direction whereas displacement acts in upward direction.  

ZERO WORK: The work done is said to be zero when force and displacement are perpendicular to each other or when either force or displacement is zero.

Example: When we hold an object and walk, the force acts in downward direction whereas displacement acts in forward direction.
