The angle between force and displacement lies between 90 degree and 180 degree , work done will be

A Force F acts on a body and displaces it by a distance S in direction at an angle theta with the direction of force ,(a) Write the expression for the work done by the force,(b)What should be the angle between the force and displacement so that the work done is (i)zero ,(ii)Maximum ?

In case of negative wark, the angle between the force and displacement is

The more the force is applied on a body to cause displacement, the more is the work done.

Force acting on a particle varies with displacement as shown in figure. Find the total work done by the force.

Asseration : All surfaces shown in figure are smooth. Block A comes down along the wedge B. Work done by normal reaction (between A and B) on B is positive while on A it is negative. Reason : Angle between normal reaction and net desplacement of A is greater than 90^(@) while between normal reaction and net displacement of B is less than 90^(@) .

The relationship between the force F and position x of body is as shown in figure. The work done in displacing the body in displacing the body from ( x = 1 m to x = 5 m ) will be .

Give Relation between Force and work.

If the angle between two vectors vecA and vecB " is " 90^(@) then

If the angle between two lines regression is 90^(@) , then it represents
