Can joules ever be negative?
Yes. A rock falling from a height has negative joules. When a displacement is in the same direction as the force the work is negative and represents exergy, energy out.I notice that the "exergy" is in red indicating it is not a word recognized by the system.This is a fundamental question in physics. Energy is energy into a system and is positive, exergy is energy coming out of the system and is negative. Exergy is like explosion and energy is like implosion. Exercise is energy coming out of the body system.
What is the name of the science that studies matter and energy?
Physics is a branch of science that focuses on matter and energy and how they interact with each other. Physics deals with subjects such as force, motion, energy, and matter.
Why is it that physics is considered as a science of energy?
queen of science maths which combines with physics to have good chemistry so physics is considered as a science of energy
What branch of physics that deals with heat energy is called?
Thermodynamics is the branch of physics that deals with heat energy.
What is another name for the study of matter and energy?
Study of matter is Physics, study of energy can be Physics or Thermodynamics
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.

Is physics the study of energy?
Physics is the study of energy including the changes of energy like force, the first derivative of energy.
What is the name of the science that studies matter and energy?
Physics is a branch of science that focuses on matter and energy and how they interact with each other. Physics deals with subjects such as force, motion, energy, and matter.
What type of science studies energy?
The study of energy would be a specialty within the field of physics, which encompasses matter, energy, space, and time.
What branch of physics deals with energy and matter?
All physics deals with energy and matter. In effect that is almost a complete definition of what Physics IS.
Is voltage negative or positive?
A negative or positive sign is applied to a current depending upon the direction in which it is moving, and in the case of alternating current, that direction changes 60 times per second. Viewed strictly as a form of energy, voltage is always positive. So far, physics has not detected negative energy.
Can work positive or Negative in physics how?
Yes Work can be positive or Negative.
When was Institute for High Energy Physics created?
Institute for High Energy Physics was created in 1963.

Advances in High Energy Physics was created in 2007.
When was Journal of High Energy Physics created?
Journal of High Energy Physics was created in 1997.
