Kinetic Energy Equation:
From: | To: |
The kinetic energy integral formula \( KE = \int v \, dp \) represents the work done to accelerate an object from rest to its current velocity, where \( v \) is velocity and \( p \) is momentum.
The calculator uses the kinetic energy formula:
Where:
Explanation: This integral formulation accounts for the relationship between velocity and momentum in determining an object's kinetic energy.
Details: Calculating kinetic energy is fundamental in physics for understanding motion, collisions, and energy transfer in mechanical systems.
Tips: Enter velocity in m/s and momentum in kg·m/s. All values must be positive numbers.
Q1: What's the difference between this and KE = ½mv²?
A: Both calculate kinetic energy. The integral form is more general and can handle cases where mass changes during motion.
Q2: When should I use this integral form?
A: Particularly useful in relativistic mechanics or when dealing with variable mass systems like rockets.
Q3: What are typical kinetic energy values?
A: Varies widely - from ~10⁻¹⁹ J for atoms to millions of joules for vehicles.
Q4: Can this be used for rotational kinetic energy?
A: No, rotational KE uses different formulas involving moment of inertia.
Q5: How does this relate to work-energy theorem?
A: The integral represents the work done to change an object's momentum.
