Answer 1

Answer:

✨Types of work:✨

*Positive Work done: Work is said to be positive when the force applied on the object is in the direction of motion of the object . *Negative Work done:work is said to be negative when the force applied on the object is opposite to the direction of motion .

Answer 2

Answer:

positive work, negative work, zero work

Explanation:

positive work:if the force and displacement are in same direction

negative work : if force and displacement are in opposite directions

zero work: if the displacement and force is zero or force and displacement are perpendicular to each other

positive work: increase in energy

negative work: decrease in energy

zero work : no change in energy
