What is work done if there is nodisplacement is 0?
Work Done = Force x Displacement, so if the displacement is zero, the work done will be zero. There will be no work done.
What is the difference between negative work and zero work and positive work done?
If the angle between the displacement and force applied is less than a right angle, then it is Positive Work done. If the angle between the displacement and the force applied is greater than a right angle then it is Negative Work done. If the displacement and force are at right angles, or either is zero, then it is Zero Work done.
When you ignite a matchstick then work will be done or not?
no work will be done because force is applied but displacement is zero so no work will be done.
When is workdone by force is zero?
work done on an object zero by a force would be zero isif the displacement of the object is zero
If displacement of a particle is zero?
If displacement of a particle is zero in a uniform circular motion, then the distance travelled by that particle is not zero, kinetic energy is constant, speed is constant and work done is zero
What force allows work to be done?
Any force can produce work if it causes displacement. If displacement is in opposite direction of force, work done will be negative and if displacement is in direction of force work done will be positive. If there is no displacement, work done is zero. Eg: Gravitational force pulls you down towards earth, in pulling you down it does work on you which gets stored in form of potential energy. Energy for A+
Where does energy goes during zero work done due to zero displacement?
energy reflects back or remains into the source.
What is positive work done?
POSITIVE work is done when the direction of displacement and gravitational force is same. This makes an angle of zero degrees. Fd?FScos0 equals +1. The work done is positive.
According to the scientific definition of work what must take place for work to be done?
Work to be done "scientifically" the product of Force and Displacement (FD) must be other than zero.
Does the string that supports a pendulum bob do work on the bob as it swings to and fro?
No. Work is force times displacement. Even though the pendulum moves, it has zero displacement in the direction of the force imparted by the string.
What is work done by a coolie walking on a horizontal platform with a load on his head?
The displacement of the load is perpendicular to the direction of force therefore work done by the coolie against the force of gravity is zero.
Can displacement be zero even if distance is non zero?
On a three dimensional basis yes it can. Fir instance, if an object is moving directly towards or away from you the angular displacement can be zero though the distance displacement changes.
