Question

write an expression for work. distinguish its three types with one example each. pls answer I will make you brainlist​

Answer 1

Answer:

To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.

Three types with example:

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

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

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