What else can I help you with?
Explain how it is possible to do no work on an object even though you have applied a force to that object.?
It is possible to do no work on an object if the force applied is perpendicular to the direction of motion of the object. In such a case, the force may cause the object to change direction but not cause any displacement in the direction of the force. Work is only done when there is displacement in the direction of the force applied.
IS THERE work can be done without any force?
No, work cannot be done without any force being applied. In physics, work is defined as the product of the force applied to an object and the distance over which the force is applied. Therefore, without force, there is no work being done on an object.
Where is force applied to an object?
A force can be applied to an object at any point on its surface or through a specific contact point. The direction of the force determines how the object will move or behave in response to the applied force.
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 is an example of work in physics?
An example of work in physics is when a force is applied to an object, causing it to be displaced in the direction of the force. Work is calculated as the force applied multiplied by the distance over which the force is applied. Work is a transfer of energy and is measured in joules.

To do work how must a force make an object move?
To make an object move, a force must be applied in the direction of the desired motion. The force should overcome any resistance, such as friction or inertia, to cause the object to accelerate and move. The force applied should be greater than any opposing forces acting on the object.
Is pushing against an immovable object is an example of work?
when force is applied and work is done In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force. for example if u climb a tree u are doing work and force is applied
Which forces can do work on an object?
Any force that causes motion or displacement in an object can do work on that object. Examples include gravitational forces, electrical forces, and magnetic forces. Work is calculated as the force applied to an object multiplied by the distance the object moves in the direction of the force.
What two conditions need to exist in order to do work?
In order to do work, two conditions that need to exist are a force must be applied on an object and the object must move in the direction of the applied force. If either of these conditions is not met, work is not being done on the object.
What two factors do you need to know to calculate how much work was done in any situation?
You need to know the amount of force applied to an object and the distance over which the force was applied in order to calculate the work done in any situation. Work is calculated as the product of force and the distance over which the force is applied, given by the equation work = force × distance.
If an object is being pushed but does not move is there any work being done on the object?
No, work is only done on an object when there is displacement in the direction of the force applied. If the object does not move, then no work is being done on it.
What must occur for work to be done on an object?
Formally, energy is required to do work. Work is technically force times distance. Thus, what must occur is a force must be applied to an object and the object must move with some movement being in the direction of the force. The quantity of work done is the "dot" product of the force vector and displacement vector. To carry out work "on an object" or in any fashion requires the same amount of energy be used as the amount of work done. (Of course, friction and other inefficiencies result in the use of more energy than the actual work done, with the excess energy taking some other form, such as heat.)
