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.

What determines whether or not work is being done?
Work is done when a force is applied to an object and it causes the object to move in the direction of the force. Mathematically, work is calculated as the force applied multiplied by the distance the object moved in the direction of the force. If there is no movement or if the force is not in the same direction as the movement, then no work is being done.
How much work is done on a 40 N rock that won't move when pushed?
Work = (force) x (distance)Without motion, there is no work, no matter how great the force.
I lift a suitcase with a force of 60 newtons of 0.5 meters. How do you know whether work was done?
Work is defined as (force) times (distance). If the force is not zero, and the distance it moved through is not zero, then work was done. In other words, if you applied a force, and kept it going while the place you applied the force moved, then work was done. In this case, work = (60) x (0.5) = 30 newton-meters = 30 joules of work.
When you burn a fuel what is released that allows work to be done?
Carbon Dioxide is release allowing work to be done.
How much work is done over 10 meters if the force is 600 newtons?
For a constant force, work = force x distance. In other words, just multiply the two. The answer is in joules.
How do wedges reduce the amount of force needed to do work?
Wedges reduce the amount of force needed to do work by increasing the distance over which the force is applied. This allows for the same amount of work to be done with less force. The shape of the wedge allows for the force to be spread out over a larger area, making it easier to split or separate objects.
How do you find distance in the formula work equals force times distance?
To find distance in the work formula, you can rearrange the formula to distance equals work divided by force. This allows you to calculate the distance by dividing the work done by the force applied.
Why can a lever is a force multiplier?
A lever can act as a force multiplier because it allows a smaller input force to generate a larger output force by increasing the distance from the fulcrum where the force is applied. This leverage advantage allows for the same amount of work to be done with less force.
Is work is always done when force is applied?
Work is only done when a force causes a displacement in the direction of the force. If the force is applied but there is no movement or displacement, then no work is done. Work is calculated as force multiplied by the distance moved in the direction of the force.
How do we know if work is done?
Work is done when a force is applied to an object and it causes the object to move in the direction of the force. The work done is equal to the force applied multiplied by the distance the object moves in the direction of the force. If there is no movement or the force is not in the direction of movement, then no work is done.
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.
What is the only condition that work is done?
Work is done when a force is applied to an object and the object moves in the direction of the force. If there is no movement, no work is done, even if a force is applied.
When force is perpendicular to the direction of motion no work is done ture or false?
True. When the force is perpendicular to the direction of motion, no work is done because work is the product of force and displacement in the direction of the force. Since there is no displacement in the direction of the force, no work is done.
How can work be done?
Work done when force moves an object.
How much work is done by a force of 500N on a stationary brick wall?
No work is done on the brick wall by the force of 500N because the wall does not move in the direction of the force. Work is only done when a force causes a displacement in the direction of the force.
When force and motion are going in the same direction is work being done?
Yes, work is being done when force and motion are going in the same direction. Work is defined as the product of force applied in the direction of motion and the distance over which the force is applied. So, when force and motion are in the same direction, work is being done.
Is there work done when an asteroid moves in space with the absence of external force?
Work is equal to Force x Distance. If no force is applied, no work is done.
