Work is considered to be zero when the force applied is zero or when there is no displacement of the object in the direction of the force.
No work is done when a force is applied to an object that does not move because work is defined as the product of force and displacement in the direction of the force. If there is no displacement, then no work is done.
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.
Since the car does not move, the boy does no work on the car. Work is only done when a force causes an object to move in the direction of the force.
The work done by the force, ( f ), to move the pendulum from ( theta 0 ) to ( theta theta0 ) is equal to the change in potential energy of the pendulum.
The answer is 0. If you used the formula of =>mgh, you would get a value which would be wrong. The question is a trick question. There is no work done in 'holding' an object but work would be done in 'lifting' an object. Hence, 0. ~Dartz
Since work= distance X force, if no distance is covered then no work is accomplished. ex/ work= distance (0) X force (1) work=1 X 0 work=0

work=force*displacement.Your are pushing a bolder & it doesn't move.So you are applying some force but 0 displacement ,0 * anything is 0.There fore work = 0.
Work = force x distance. If distance = 0, work = 0 because force x 0 = 0.
0 because you are not moving it work = force * distance work = wight of book * 0(no movement)
06= 0x0x0x0x0x0= 0
That is called the machine's efficiency. It is a number between 0 and 1 (or between 0% and 100%).

No work is done when a force is applied to an object that does not move because work is defined as the product of force and displacement in the direction of the force. If there is no displacement, then no work is done.
0+0 is always 0 0-0 is always 0 0*0 is always 0 0/0 is undetermined, and can basically be any value. 0^0 is a bit fuzzy. It's often used as 1 because it makes equations work.
his formula does not work because if you get a cone it adds up to 0
