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.
Joule is a unit of energy and heat, not a temperature.
No. It is not reasonable. If that ever happened, we would have to ask where the additional 40 joules came from, since energy cannot be created or destroyed. If there were something inside the box that added 40 joules to the 110 passing through, then that 40 would need to be added to the "input" work.
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
joules are the amount of energy
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
BTU x 1,055.056 = joules
yes!
yes it can be negative.

56 kilo joules = 56,000 joules
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
0 J, Joules is in N*m or kg*(m^2)*(s^(-2)). The question you asked will not have any units as any dimensions within an exponent disappear.
A petajoule is 1015 joules (Quadrillion joules)
Yes, if you are averaging numbers that include negative numbers.
4.18400 joules = 1 calorie, so 12.552 joules = 3 calories
Negative, ghostrider.
no
Yes.
