Question

Define work and explain three types of work​

Answer 1

Answer:

There are three types of work. 1.Positive work- when the force and the displacement are in the same direction(theta=0 degrees) 2.Negative work- When the force and the displacement are in the opposite direction(theta=180 degrees) 3.Zero work- When the applied force does not cause displacement(theta=90 degrees)

Answer 2

Answer:

Work is said to be done when a force acting on a body displaces it through a certain distance. The work by a constant force is measured by the dot product of force will displacement.

There are three types of work

1.Positive work- when the force and the displacement are in the same direction(theta=0 degrees)

2.Negative work- When the force and the displacement are in the opposite direction(theta=180 degrees)

3.Zero work- When the applied force does not cause displacement(theta=90 degrees)
