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.

Is it reasonable to have a work output of 150 Joules when work input is 110 Joules?
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.
Can acceleration ever be negative?
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
What is joules in science?
joules are the amount of energy
How many joules are in 55.2 calories?

How many joules are in 56 kilo joules?
56 kilo joules = 56,000 joules
How do you convert from killi joules to 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.
How many joules in 1.09677610 to the power of 7 moles to the power of negative 1?
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.
How many joules in a petajoule?
A petajoule is 1015 joules (Quadrillion joules)
Can the mean ever be negative?
Yes, if you are averaging numbers that include negative numbers.
How do you Convert 3 calories to joules?
4.18400 joules = 1 calorie, so 12.552 joules = 3 calories
Will conner ever ask you out?
