Direction of force and displacement should always be same for a non zero work.
Choose the correct option according to the angle between force and direction of displacement.
Coloumn 1Coloumn 21.θ is zeroi) Work done is always zero2.θ is less than 900ii)Work done is non-negative3.θ is greater than 900iii) Work done is always positive4.θ is 900iv) Work done is never positive
A force F acts on a body and displaces it by a distance S in a direction at an angle θ 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 to get (i) zero, (ii) maximum, work?
A non-zero force is acting on a body but work done is zero. Which of the following statements justify the above situation? 1.Displacement is zero. 2.Force is perpendicular to the direction of displacement. 3.Force is parallel to displacement. 4.Force is opposite to the direction of displacement.
