Final answer:
The formula for work when force and displacement are in the same direction (θ=0) is W = Fd, and the work done is positive.
Step-by-step explanation:
When θ=0 and the force is in the same direction as the displacement, the formula for work is W = Fd cos(θ), where W is work, F is the magnitude of the force acting on the object, d is the displacement of the object, and θ is the angle between the force and the displacement.
Because θ is zero degrees and the cosine of 0 is 1, the equation simplifies to W = Fd. This indicates that the work done is positive, as the force and displacement are in the same direction.
The formula for work is given by the equation W = Fd cos θ, where W is the work done, F is the force applied, d is the displacement, and θ is the angle between the force and displacement.
In this case, θ = 0 and the force is in the same direction as the displacement. As a result, the formula for work simplifies to W = Fd.
Since the force and displacement have the same direction, the work done is positive.
