Work is minimized when the angle between the force applied and the direction of motion is 90 degrees (or π/2 radians). At this angle, the force does not contribute to the displacement in the direction of the force, resulting in zero work done. In general, as the angle increases from 0 to 90 degrees, the work done decreases, reaching its minimum at 90 degrees.

What is the minimum amount of acute angles a triangle can have?
A triangle can have a minimum of zero acute angles, which occurs in the case of a right triangle (which has one right angle) or an obtuse triangle (which has one obtuse angle). Therefore, it is possible for a triangle to have no acute angles at all.

What is the angle of minimum deviation in a diffraction experiment?
The angle of minimum deviation in a diffraction experiment is the angle at which the diffracted light rays are the most spread out, resulting in the best separation of the different colors. It is typically smaller than the angle of the first diffraction minimum to achieve maximum dispersion.
What is minimum firing angle?
It means the minimum current can trigger the SCR to operate.
What can be said about a situation in which work done is negative?
the formula F.S cos angle is used (the dot product) so if angle is 0,cos angle=1 hence work done is positive and maximum if angle is 90 so cos 90 is 0 hence work done is minimum if work done is negative the angle is 180 The work done by friction is always negative (opposite the force) Since work is force x displacement, a negative value for work could mean that the displacent was negative
Why should you keep the prism in minimum deviation position?
f a line is drawn parallel to the angle of incidence axis (X-axis), it cuts the graph at two points, showing that there are two values of angle of incidence for an angle of deviation. However, at the point of angle of minimum deviation, the line will be tangent to the curve showing that for minimum angle of deviation there is only one angle of incidence.
Why does the angle of deviation of a prism decreases first and then increases?
As the angle of incidence is increased, angle of deviation 'd' decreases and reaches minimum value. If the angle of incidence is further increased, the angle of deviation is increased. Let dm be the angle of minimum deviation. The refracted ray in the prism in that case will be parallel to the base.
Angle between force and displacement to get minimum work?
The work done by a force is the dot product of the force and the displacement of the point of application of the force i.e.component of force in the direction of displacement * displacementorcomponent of displacement in the direction of force * forcelet W be the work done. Then :W = F.SW = |F|*|S|*cos(θ) ---- equation 1where F and S are force and displacement in vector form and |F|, |S| are their magnitudes respectively. cos(θ) is the angle between line of action of force vector and displacement vector.It is clear from the equation 1 that work will be minimum when cos(θ) is minimum. It is known from trigonometry that minimum value of cos(θ) is -1 which is for angle 1800 or π radians. So work done will be minimum when angle between force and displacement vector is π radians or 1800 i.e. when point of application of force is displaced exactly opposite to the direction of application of force.I appreciate the last attempt to answer the question, but I think it is wrong. The answer should be 90°, because although cos180° = -1, the negative sign in- FScos180° only signifies that the work done has taken away energy from the system, or it signifies that the work is done in the opposite direction, implying that work is done. When the angle is 90°, on the other hand, work done = 0, ie, no work is done at all. Thus the answer should be 90°.(The above answers define minimum work differently.The first answers is if minimum work is negative work, therefore if you do work in the opposite direction of the displacement, the work you do is negative and is less than 0. Minimum work here is the work that is the lowest number.The second answer defines minimum work as the magnitudeof the work done being minimized. Since magnitude is always positive, minimum work in this case would always be zero. Which one is correct depends on the situation you are dealing with.)
What should be the angle between force and displacement to get the minimum work and maximum work?
To minimize work, the angle between force and displacement should be 90 degrees (perpendicular). This is because work done is calculated as the dot product of force and displacement vectors, and the cosine of 90 degrees is 0, resulting in zero work. To maximize work, the angle should be 0 degrees (parallel), as the cosine of 0 degrees is 1, resulting in maximum work done.

What is the minimum work needed to push a 900kg car 960m up along a 7.5 incline?
The minimum work needed can be calculated using the formula: work = force x distance. The force required to push the car up the incline can be calculated using the formula: force = weight x sin(angle). Plugging in the values gives minimum work = force x distance.
