What else can I help you with?
What is The work done holding a 50 kg object at a height of 2 m above the floor for 10 seconds?
The answer is 0. If you used the formula of =>mgh, you would get a value which would be wrong. The question is a trick question. There is no work done in 'holding' an object but work would be done in 'lifting' an object. Hence, 0. ~Dartz
Can work be done if there is no motion?
Yes, work can still be done even if there is no motion. Work is defined as the force applied over a distance, so as long as there is a force acting on an object in the direction of the force, work is being done. If an object is stationary but has a force applied to it, work is still being done even though there is no motion.
If a force of 100 newtons was exerted on an object and no work was done the object must have?
If no work was done, the object must not have moved in the direction of the force. This could happen if the force was applied perpendicular to the object's motion or if the object remained stationary.
In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.
What are some examples of situations where no work is done?
Some examples of situations where no work is done include holding a book in a stationary position, pushing against a wall that does not move, and carrying a backpack while standing still. In these cases, although there may be physical effort involved, no work is being done because there is no displacement of an object in the direction of the force applied.
Is holding a pencil work or not?
No, work is only done when an object is moved.

Why is no work done no an object when a force acting on the object dose not move?
It's a play on words (try holding a weight steady at arms length) that's totally dependent on the definition of "work".
When can you say that work is done on an object?
when a force acts to move an object,we say that work was done on the object
What are some examples of situations where no work is done?
Some examples of situations where no work is done include holding a book in a stationary position, pushing against a wall that does not move, and carrying a backpack while standing still. In these cases, although there may be physical effort involved, no work is being done because there is no displacement of an object in the direction of the force applied.
True or false work is done only when an object moves in the direction of the applied force?
False. Work is done whenever a force is applied to an object and there is a displacement in the direction of the applied force, whether the object moves in that direction or not. In cases where the object does not move, work is still done as long as there is a force applied over a distance.
When is work not done on an object?
Work is not done on an object when there is no displacement of the object in the direction of the force applied. In other words, if the force and the displacement are perpendicular to each other, no work is done. Additionally, if there is no force acting on an object, no work is being done on it.
Is work done if an object does not move?
No, work is defined as the force applied to an object multiplied by the distance the object moves in the direction of the force. If the object does not move, then work is not done on the object.
Where do you say that work is done an object?
Work is done on an object when a force is applied to the object and the object moves in the direction of the force. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.
