Question

Draw p-v diagram and the explain the concept of positive and negative work will give one example each

Answer 1

Answer:

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

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 forward direction. So,work done is positive.

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 forward 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.

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 forward 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 CTS in downward direction whereas displacement acts in upward direction.

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 forward 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 CTS in downward direction whereas displacement acts in upward direction.ZERO WORK:The work done is said to be zero work when force and displacement are perpendicular to each other or when either force or displacement is zero.

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 forward 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 CTS in downward direction whereas displacement acts in upward direction.ZERO WORK:The work done is said to be zero work 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......
