What else can I help you with?
Is it possible for the total work done on an object to be negative?
Yes, it is possible for the total work done on an object to be negative. This occurs when the force applied to the object is in the opposite direction of its displacement.
How much work is done if a force of 20 N is applied on an object that remains stationary?
No work is done because work is the product of force applied and displacement in the direction of the force. Since the object remains stationary, there is no displacement in the direction of the force, so no work is done.
Is it possible to perform negative work?
Yes, it is possible to perform negative work. Negative work occurs when the force applied to an object is in the opposite direction of the object's displacement. This results in the object losing energy rather than gaining it.
When you work on an object you increase the what of the object?
When you work on an object, you increase the energy of the object. This can be in the form of kinetic energy (if the object is in motion) or potential energy (if the object is at rest but has the potential to do work).
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.
What action would require no work to be done on an object?
If no work is done on an object, it either remains at rest or continues in motion without any force being needed. In this case there is no action-so the question seems meaningless.
Is it possible for the total work done on an object to be negative?
Yes, it is possible for the total work done on an object to be negative. This occurs when the force applied to the object is in the opposite direction of its displacement.

Work is only done when there is displacement in the direction of the force applied.
What must happen to an object if a force does not work on it?
If a force does not work on an object, the object will either remain at rest or continue moving at a constant velocity in a straight line, according to Newton's first law of motion.
What is the work of a motionless object?
Work = Force x Displacement Therefore the work in a motionless object would be 0.
What is an example of inertia at work?
An example of inertia at work is when a moving object continues moving in a straight line at a constant speed, or when a stationary object remains at rest, unless acted upon by an external force. This principle demonstrates how objects tend to resist changes in their state of motion.
How is it possible to apply force to something but do no work?
Work is calculated as force multiplied by the distance the force is applied over. If the force is applied but the object does not move, no work is done because there is no displacement. So, it is possible to apply force without doing work if there is no movement of the object.
Can you explain if it is possible to do negative work in a physical system?
Yes, it is possible to do negative work in a physical system. Negative work occurs when the force applied to an object is in the opposite direction of its displacement. This results in the object losing energy rather than gaining it.
An object of mass 'm' is moving with the constant velocity 'v' how much work should be done on the object to bring it to rest?
An object with mass 'm' moving with velocity 'V' has kinetic energy of [ 1/2 m V2 ] .In order to bring it to rest, its velocity has to be reduced to zero, and in order toaccomplish that, the kinetic energy has to be drained off and sent somewhere else.An external force has to absorb energy from the object, i.e. do negative work on it,equal to its kinetic energy, or- 1/2 m V2
