This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
If there is no motion, can there still be work done on a system? Due to the nature of the working definition, the answer is no.
Is it possible to accomplish work within a system?
Imagine a simple compressible substance
Work is done by the system whenever its volume expands in the face of an opposing force. Work is done on the system if the volume of the system decreases while it is being affected by a force.
Can work done be zero?
When the displacement of a body is either zero or perpendicular (=900,cos=0) to the direction of the force that is being applied, then the amount of work that is being done is zero…. Hence, the direction of the applied force and the direction of the displacement are perpendicular to one another. Hence, there was no work accomplished.
Is it conceivable for a system to have a deficit?
Is it conceivable for a system to have potential energy that is in the negative? a. In this case, the answer is yes, provided that the kinetic energy is positive.
If there is no acceleration, has the work been completed?
Explanation: If anything is going in the same direction at the same speed all the time, then by definition that thing has no acceleration… Hence, the sum of the work done on the item is zero (this does not mean that there is no work done on the object by the various forces acting on it; however, the total amount of work is zero).

Is the work completed or not?
Work is done when a force (F) that is applied to an item causes that object to move in a direction that is parallel to the direction in which the force is applied… • You’ve got it right—this scenario is a representation of work—a guy is lifting a box so that it can be put on a table.
What is the equation for the work that has been done?
In the world of science, the formula for work done will be presented as W = F * d: In this scenario, the force that is being applied to the block remains unchanged; however, the direction of the force and the direction of the displacement that is being influenced by this force are not the same.
Can a system have 0 energy?
A system’s kinetic energy can only ever be in either the positive or the negative… Because its value is relative to a particular point, the potential energy of a system has the possibility of being negative.
Is it really feasible for a system to have energy if there is no motion taking on within the system?
Is it really feasible for a system to have energy if there is no motion taking on within the system? Yes. One example of such a system is one in which all of the system’s energy exists solely in the form of potential energy. The position of an object with relation to a fixed point determines its potential energy.
Is it conceivable for a system to have more negative mechanical energy than it does positive mechanical energy?
A negative form of mechanical energy is possible. The total amount of kinetic energy and potential energy is referred to as mechanical energy.
In what circumstances might the amount of work done be zero?
Work that has been done is stated to be zero when the force that is being applied to the body is also zero, or when the displacement that has been done by the body is also zero. If the value that indicates the force acting on the body is perpendicular, then the force acting will be equal to zero if the body is being acted upon.
What exactly does it mean when there is no work being done?
If the displacement is either zero or perpendicular to the direction of the force, then the work done by the force is zero. When the force and displacement are in the same direction, the work done is positive, but it is negative when the force and displacement are in the opposite direction.
When will we be able to state that no work remains?
If we were to quantify the work that was done, the result would be zero because the degree ofcos90 Cos90 is also zero. Because of this, it is safe to say that no work is being done whenever the force vector and the displacement vector are aligned in a direction that is perpendicular to one another. Thus, the choice B is the one that should be chosen as the response.
What kind of progress has been made on the system and the example?
When the gas is expanding on the piston, and the piston is moving outwards, this is an example of work that is being done by the system.
Why does working on a system result in a negative outcome?
The fact that the PV work done has a negative sign attached to it shows that the system is losing energy. If the volume grows while the pressure remains the same, which is denoted by the expression “V > 0,” then the work done by the system is negative. This indicates that the system has expended energy in the process of performing work on its surroundings.
Is the progress made on a system beneficial?
As energy departs a system, the sign of that energy becomes negative. A favorable indicator for the system is the completion of work on it. A negative sign is assigned to the system if it is the one that performs the labor.
Is it feasible for a system to have a potential energy that is in the negative? quizlet
Is it conceivable for a system to have potential energy that is in the negative? Because the position of the potential energy zero can be chosen at will, the answer is yes.
Which of the following best describes the type of energy that is linked with the motion of an object?
Kinetic energy is the name given to the form of energy that is related with the motion of an item.
To what extent may the work done by a frictional force ever contribute to an increase in the system’s total mechanical energy?
Because of the frictional force, it is NOT feasible to raise the total amount of mechanical energy that the system possesses.
What exactly are the three laws that govern energy?
The first law of thermodynamics, the second law of thermodynamics, and the third law of thermodynamics are the three fundamental laws that have traditionally been recognized within the field of thermodynamics…. According to the third rule of thermodynamics, the entropy of a system will tend toward a value that is constant as the temperature moves closer and closer to absolute zero.
Is it possible to generate matter?
Hence, matter can be formed by combining two photons together. This threshold energy must be greater than the total rest energy of the fermions that are formed in order to satisfy the requirements of the law of energy conservation, which states that a minimum amount of photon energy is necessary for the generation of a pair of fermions.
Are we formed up of energy in some way?
Energy is the fundamental component of not only matter but also all psychological processes, including thoughts, feelings, beliefs, and attitudes. When applied to the human body, each atom, molecule, cell, tissue, and body system is formed of energy that, when overlaid on each other, creates what is known as the human energy field. When applied to the human mind, every thought you have is composed of energy.
What does the completion of work amount to?
When work transmits energy to a body, the increase in the body’s total energy is proportional to the amount of work that is done on the body. If, on the other hand, the force that is being applied is in opposition to the motion of the item, then the work that is being done is said to be negative. This indicates that energy is being extracted from the object.
How do I compute resistance?
Using Ohm’s Law, you can calculate the total resistance of a circuit if you already have the total current and the voltage across the entirety of the circuit. R = V / I. An illustration of this would be a parallel circuit with a voltage of 9 volts and a total current of 3 amps. The overall resistance, denoted by RT, is equal to 9 volts divided by 3 amps, or 3 ohms.
When will the work actually be finished?
The completion of a task occurs whenever anything moves from one location to another. An additional method of expressing work that can be used to convey this concept is the equation W=E, in which E refers to the total energy present in the system.
