Question

Answer the following
write the general expression for work in terms of force
displacement and angle between
two. Hence, write the
condition under which work done is
positive, zero, negative?​

Answer 1

Answer:

Since the angle between the force and displacement is 180 degrees, the work done by the gravitational force on the body is negative. Diagrammatic representation is given. Hence for negative work done, angle between force and displacement is 1800.
