Conservation Of Energy Formula:
| From: | To: |
The conservation of energy principle states that energy cannot be created or destroyed, only transformed from one form to another. In calculus, this is represented by the integral of differential energy being equal to zero: ∫ dE = 0.
The calculator demonstrates the conservation of energy principle:
Where:
Explanation: The integral of differential energy over any closed system equals zero, confirming that energy is conserved in the system.
Details: The conservation of energy is a fundamental principle in physics that applies to all physical systems. It's essential for analyzing mechanical systems, thermodynamic processes, and energy transformations in various physical phenomena.
Tips: Enter the differential energy value (dE) in Joules. The calculator will demonstrate that the integral of differential energy equals zero, confirming energy conservation.
Q1: What does ∫ dE = 0 mean physically?
A: It means that the total energy change in a closed system is zero - energy is neither created nor destroyed, only transformed between different forms.
Q2: Does this apply to all types of energy?
A: Yes, the conservation principle applies to all forms of energy including kinetic, potential, thermal, chemical, and nuclear energy.
Q3: What are the units of differential energy?
A: Differential energy (dE) is measured in Joules (J), the same as energy.
Q4: When is energy not conserved?
A: Energy is always conserved in isolated systems. Apparent non-conservation typically occurs when energy transfers to/from the environment aren't accounted for.
Q5: How is this different from the first law of thermodynamics?
A: The first law of thermodynamics is essentially a statement of energy conservation, specifically applied to thermodynamic systems where heat and work are considered.
