What else can I help you with?
Explain - how you can exert a large force on an object without doing any work?
You can exert a large force on an object without doing any work by pushing against an immovable wall. In this scenario, although a large force is applied, no work is done because there is no displacement of the object in the direction of the force. Work is only done when there is both a force and displacement in the same direction.
If a pencil drops from a desk is work being done WHY?
No, work is not being done when a pencil drops from a desk. In physics, work is defined as force applied over a distance in the direction of the force. Since the force of gravity causes the pencil to fall vertically without any horizontal displacement, there is no work being done in this scenario.
Is any work done by pushing wall?
No, pushing against a wall does not result in any work being done. Work is only done when a force causes an object to move in the direction of the force, so if the wall does not move, no work is done.
How you can exert a large force on an without doing any work?
You can exert a large force on an object without doing any work by exerting the force perpendicular to the direction of motion. In this case, no work is done because the force does not act in the direction of the object's displacement. This situation is commonly seen in scenarios involving static friction or when lifting an object vertically.
When does a force applied to an object not do any work?
A force does not do any work on an object when the object does not move in the direction of the force or when the force is perpendicular to the direction of motion. Work is only done when there is displacement in the direction of the force.

Do all forces of an object cause work to be done?
No, work is only done by a force when there is displacement in the direction of the force. Forces that do not cause any displacement, such as static friction or normal force, do not do work on an object.
How can you tell if a force you exert is doing work?
Work is done when a force is exerted on an object and that force causes the object to move in the direction of the force. If the object moves, then work is being done. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.
Work done by a constant force?
There is motion but it is non- uniform motion. It cannot be seen by us because it's motin is very slow
What is the work done when a force will be applied on body in absence of any other force?
infinite
A force at any angle to the direction of motion can perform work?
Yes, a force can perform work at any angle to the direction of motion. The work done is determined by the component of the force that is in the direction of motion, not the total force itself. This component is what contributes to the displacement of the object and thus the work done on it.
Distinguish cases when work is done and when it is not?
The cases when work is done and when it is not are quite distinct. Where work is done, the task is completed to satisfaction but where it is not, it means it has either not been started or it has been done below standard.
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+
