If you apply force in the same direction an object moves, the work on the object is positive.If the force is in the opposite direction as the direction the object moves, the work on the object is negative.

What is negative energy in physics?
what I mean is, the alcubierre drive needs negative energy to work so what are the properties of negative energy
Work is done when in physics?
In physics, work is done when a force is applied over a certain distance.
Why experiment in physics?
To find out how things work; to confirm or reject ideas about physics.
How did Newton's interest in alchemy further his work in physics?
Newton's work in physics was based on his interest in alchemy. That interest led him to experiment and in doing so, it resulted in his discoveries about physics.
In physics is work equal to the negative of the potential energy?
Yes, work= -GmM/R This work is energy that is stored in the gravitational field of the two masses and is called the gravitational potential energy of the two masses when they are separated by a distance R: Ep= -GMm/R
Can work positive or Negative in physics how?
Yes Work can be positive or Negative.

Can torque have a negative value in physics?
Yes, torque can have a negative value in physics. Torque is vector energy. Torque is the vector analogue of Work involving force (F) and displacement (D) vectors and the angle (FD). For example Work W = -F.D= -|FD|cos(FD) and Toque T = FxD =|FD|sin(FD). Torque can be negative dependent on the sine(FD). Work and torque is an example of the quaternion nature of physics; for example Quaternion energy E = FD = -F.D + FxD, the real energy is called work F.D and the vector energy is called torque, FxD.
What is work in physics?
in physics work work=force *distance the distance covered by body by any force is called work.
Where do physics work at?
Physics works in the whole of the universe.
Work is done when in physics?
In physics, work is done when a force is applied over a certain distance.
How physics work?
Physics doesn't really "work". What it does is "describe" - it describes the way our world works, as far as we know.
Where can you get positive and negative wires for a class project?
You can get the positive and negative wires for a class project at a store that sells the Physics apparatus.
Why experiment in physics?
To find out how things work; to confirm or reject ideas about physics.
Can work done by a force be negative?
Yes. If force is negative, then work will be negative.
