How do you determine a work done is positive sign or negative sign?
If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.
Is a negative a positive is what?
A Negative plus a positive = a negative because negative and a positive cannot work together Negative + Negative= Positive Positive + Positive = Positive when your dealing with numbers such as : -2 + 2 would equal a negative 4 -2 +-2 would equal a positive 4
What is 63 divided by negative 7?

Does gravity do positive or negative work on falling objectexplain?
It does positive work. There's 2 ways to look at this: 1) This one's a chemistry way. When work is done on a system by the surroundings, the work is positive. When the system itself is doing work on the surroundings, this is negative work. Just think of it in terms of the system. It gains energy when something does work to it and loses energy when it works on something else. Based on this, do you think it's positive or negative work? 2) This one's a physics way. W = Fd cos (theta). In this equation, W = work, F = a force, d = displacement, and theta = angle between the force and the displacement. So, let's take the example of a falling object. As it falls, the force of gravity is exerting a force towards the ground. The object is moving towards the ground also. Since both the directions are the same, theta is 0 and work is + (cos of angle 0 is +1). When the object is moving upward while gravity is acting on it, exerting a downward force, the angle between them is 180 degrees. At 180 degrees, cos is -1. Work done by gravity is negative in this case. Either ways, positive work is being done by gravity on the falling object.
A positive and negative comment at the same time?
Today is not an unpleasant day.You'll be lucky if you can get this man to work for you.
How do you determine a work done is positive sign or negative sign?
If work is done on the system then it has a negative sign. If work is done by the system then it has a positive sign.
When do you say that the work done is positive or negative?
There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.
Is the work done by the system is considered as positive or on the system is considered as positive?
Work done by the system is considered as PositiveWork done on the system is considered as Negative
When work is positive and when is negative?
when work is positive and when playing is negative
Can work positive or Negative in physics how?
Yes Work can be positive or Negative.
What is the difference between negative work and zero work and positive work done?
If the angle between the displacement and force applied is less than a right angle, then it is Positive Work done. If the angle between the displacement and the force applied is greater than a right angle then it is Negative Work done. If the displacement and force are at right angles, or either is zero, then it is Zero Work done.
Should positive go to positive in a circuit?
No, this will not work. Postitive to Negative/Negative to Positive will work.
What are positive and negative work ethics?
what is positive and negative
What can be said about a situation in which work done is negative?
the formula F.S cos angle is used (the dot product) so if angle is 0,cos angle=1 hence work done is positive and maximum if angle is 90 so cos 90 is 0 hence work done is minimum if work done is negative the angle is 180 The work done by friction is always negative (opposite the force) Since work is force x displacement, a negative value for work could mean that the displacent was negative
In one complete orbit is the work done by the earth on the space station positive negative or zero?
zero
When the force acting on an objects points at least partially in the blank direction of the motion the work done is considered to be what?
Positive work is work done in the direction of motion, while negative work is work done in the opposite direction from the motion.opposite
Can work done by a force be negative?
Yes. If force is negative, then work will be negative.
