Can total work done on an object negative?
Yes, the total work done on an object can be negative. This occurs when the force applied to the object is in the opposite direction to the displacement of the object. In this case, the work done is considered negative.
When negative work is done on a moving object it's kenetic energy?
When negative work is done on the object, the object's energy decreases. This MAY be kinetic energy, but some other form of energy may increase instead, for example, potential energy or heat energy.
Is the work done by friction always negative?
No, the work done by friction can be either positive or negative, depending on the direction of the force and the displacement of the object.
When is change in energy always negative?
A change in energy is always negative when an object loses energy, such as when work is done against friction or when heat is transferred away from the system. This results in a decrease in the object's total energy.
How can the concept of work be negative in the context of physics?
In physics, work is considered negative when the force applied to an object is in the opposite direction of the object's displacement. This means that the force is doing work against the motion of the object, resulting in a negative value for the work done.

What does substantial indemnity mean?
To imdemnify is to replace something to its original status before something caused some negative status to said object/product. Sustantial means it will replace said object product as near as is possible and reasonable to be done.
What is negative work in physics and how does it affect the overall energy of a system?
Negative work in physics occurs when the force applied to an object is in the opposite direction of its displacement. This results in a decrease in the object's energy, as work is done against its motion. In terms of the overall energy of a system, negative work reduces the total energy by converting it into other forms, such as heat or sound.
What could be the negative word for possible?
The negative word for possible is usually "impossible," meaning that something cannot be done or achieved under any circumstances.
Why is gravitational potential energy negative?
Gravitational potential energy is negative because it is defined as the work done by gravity when an object moves from an infinite distance away to a certain point in a gravitational field. The negative sign indicates that work is done by gravity on the object as it moves closer to the source of gravity.
Work done in lifting and lowering an object?
The work done in lifting an object is positive, as energy is input to move it against gravity. The work done in lowering an object is negative, as the object is moving in the direction of the force of gravity, and energy is being released. Overall, the work done will depend on the distance the object is lifted or lowered and the force applied.
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.
Why gravitational potential is negative?
Gravitational potential is considered negative because work needs to be done to move an object from an infinite distance to a certain point in the gravitational field. As the object moves closer to a massive body, the potential energy decreases, resulting in a negative value to reflect the work done against the gravitational force.
