Is the work done on a system negative in the given scenario?
In the given scenario, if the force applied to the system is opposite to the direction of the displacement, then the work done on the system is negative.
How can one determine the work done by friction in a given scenario?
To determine the work done by friction in a scenario, you can calculate the force of friction acting on an object and multiply it by the distance the object moves in the direction of the frictional force. This will give you the work done by friction in that scenario.
When is workdone by force is zero?
Work done by a force is zero when the force is applied perpendicular to the direction of motion of the object. Another scenario is when the force is applied but there is no displacement of the object.
You push a couch 8 meters across the floor with a force of 200 N How much work have you done?
Work is a force applied over a distance.So W=F*dThus in this case, W=200N*8mWork=1600 N*m3,000 J
How will you know that work is done on an object?
Work is done on an object when a force causes the object to move in the direction of the force. The amount of work done is calculated by multiplying the force applied by the distance the object moved in the direction of the force. Work done transfers energy to or from the object, causing a change in its kinetic or potential energy.
Is the work done on a system negative in the given scenario?
In the given scenario, if the force applied to the system is opposite to the direction of the displacement, then the work done on the system is negative.

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.
How do you find work done if force and mass are given?
You cannot. You do not have the necessary information.
If you push for an hour against a stationary wall you do no work why?
Work is calculated as force multiplied by displacement in the direction of the force. In this scenario, since the wall doesn't move, there is no displacement in the direction of the force. Therefore, no work is done on the wall.
How much work does Paul's force do during a displacement of the crate that is 12.0 m?
The work done by Paul's force is given by the formula Work = Force x Distance x cos(theta), where theta is the angle between the force and the direction of displacement. If the force is in the same direction as the displacement, then theta = 0 and the work done is simply Force x Distance. If the angle is not given, assuming theta = 0, the work done is the force times the distance.
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 do you get work done if you have given mass and power?
To calculate work done when given mass and power, you need to know the force applied and the distance over which the force is applied. Work done is calculated as the product of force, distance, and the cosine of the angle between them. Power is the rate at which work is done, so you can calculate it by dividing the work done by the time taken to complete the work.
How do you find output force if you are only given efficiency and work?
You can find the output force by dividing the work done by the input force by the efficiency. This formula is: Output Force = Work / (Input Force * Efficiency).
