Tiwari Academy Discussion Latest Questions
A force must act on an object, and the object must be displaced.
These examples illustrate that work involves both force and movement in the direction of the force, aligning with the scientific definition that work equals force times distance.
No, work is not done if there is no displacement, even if force is applied.
The two key components are the exertion of force and the displacement of the object.
Work is indicated by the trolley moving through a distance due to the force exerted by the girl.
The pebble must be moved through a distance by an exerted force.
The work done would be zero if either the force F is zero, the displacement s is zero, or if the force is not acting in the direction of the displacement (assuming there is no component of the force in ...
The formula for work when the force and displacement are in the same direction is = × W = F × s, where W is the work done, F is the force, and s is the displacement.
The work done W is calculated by multiplying the force F by the displacement s: = × W=F × s.
