Kinetic Energy To Velocity Equation:
| From: | To: |
The Kinetic Energy To Velocity equation calculates the velocity of an object based on its kinetic energy and mass. It is derived from the kinetic energy formula KE = ½mv² and rearranged to solve for velocity.
The calculator uses the equation:
Where:
Explanation: This equation calculates the velocity of an object by taking the square root of twice the kinetic energy divided by the mass.
Details: Calculating velocity from kinetic energy is important in physics and engineering applications, including motion analysis, collision studies, and energy conservation calculations.
Tips: Enter kinetic energy in joules (J), mass in kilograms (kg). All values must be valid (KE > 0, mass > 0).
Q1: What units should I use for this calculation?
A: Use joules (J) for kinetic energy and kilograms (kg) for mass to get velocity in meters per second (m/s).
Q2: Can this equation be used for relativistic speeds?
A: No, this equation is based on classical mechanics and is not accurate at relativistic speeds approaching the speed of light.
Q3: What if the mass is zero?
A: Mass cannot be zero in this equation as it would require division by zero, which is mathematically undefined.
Q4: Does this equation account for direction?
A: No, this equation calculates speed (magnitude of velocity). Velocity direction would need to be determined from additional information.
Q5: Can I use this for objects with rotational energy?
A: This equation calculates linear velocity from translational kinetic energy only. For objects with significant rotational energy, additional calculations are needed.
