WebFor angle θ = 0°, the work done is positive, so it is not true. For angle θ = 45°, W = F.d/√2. In this case also, work done is positive, so it is not true. Work done at θ = 90°, W = 0. So, it is not true. Now, work done at θ = 180°, W = -F.d. For negative work, the angle between the force and displacement should be 180°. WebNegative work is done when the displacement is in the opposite orientation of the force delivered. Example: The gravity on some kind of rocket moving vertically upwards was worked on. Zero work: Whenever force and displacement, are perpendicular to one another, or even when either force or displacement is zero.

WebJul 27, 2024 · The formula you have supplied in your question says it all: F → ⋅ r → = F r c o s ( θ) F and r are both positive (vector magnitudes), and so the negative sign comes from c o s ( θ) θ is the angle between the vectors, and c o s ( θ) is negative when π 2 < θ < 3 π 2. WebCosine is greatest when the angle is zero (the angle between two vectors pointing in the same direction is zero), zero at ninety degrees (forces perpendicular to displacement do no work), and negative for obtuse angles (forces acting opposite displacement undo work). Work is best defined by an equation. Here's one common version…
