What is the work done when there is no displacement?
The work done is zero if there is no displacement. Displacement is the change in position of an object, measuring from its starting and final position. Power is defined as the rate at which energy is transferred or work is done.
Is it possible that displacement is zero but?
Yes. For example, a car travels from point A to B and then comes back. Suppose AB=5m. In this case, distance travelled is 10m, while the displacement is zero.
What is the work done if a force causes zero displacement?
Explanation: Work in Physics is said to be done when the objects gets displaced from its initial position when force is applied on it or their in increase in the object’s kinetic energy. If displacement = 0, then velocity and hence kinetic energy = 0 and hence no work is done.
Is the work done by a body when displacement of a body is zero?
Zero work is done when the displacement of a body is zero or perpendicular (θ=900,cosθ=0) to the direction of force applied, then work done is zero.
Can work be done in the absence of motion?
A) Energy conservation law for a projectile (no friction): Potential energy decrease equals the kinetic energy increase. B) More power is required while slowly lifting a box than while lifting it up quickly. C) Work cannot be done in the absence of motion.
Is displacement zero True or false?
True. After travelling some distance , distance can’t be zero. But , displacement can be zero if we retrace the path and reach the initial starting point.
What is the work done if there is no displacement?
To simply state an answer to each question: No displacement = no work done. the definition of work is when a force acts on an object to displace it. Yes, you can calculate the work done by each force.
Why is the work done by each Force Zero?
If the displacement of the object is zero, then one cancalculate the work done by each individual force, the work done by eachforce is zero. Why? Work is not defined in terms of what would have happened to the object in the absence of other forces; it is defined in terms of the motion that actually occurred.
What is the work done by each force on the mass?
Note that because there is no displacement, the value of the applied forces are equal. Each force applies work to the mass. In conclusion, no work is done. We can calculate the work done by each force, but usually that is only used for proof that no work is done.
Can work done by a force be negative or positive?
As a result, the work done by a force can be positive, negative, or zero, depending on whether the force is generally in the direction of the displacement, generally opposite to the displacement, or perpendicular to the displacement.
