Velocity Formula:
| From: | To: |
The velocity formula calculates the speed of an object based on its kinetic energy and mass. It is derived from the kinetic energy equation and provides a direct relationship between these physical quantities.
The calculator uses the velocity formula:
Where:
Explanation: The formula shows that velocity is proportional to the square root of the ratio of twice the kinetic energy to the mass of the object.
Details: Calculating velocity from kinetic energy and mass is essential in physics and engineering applications, particularly in mechanics, energy conservation problems, and motion analysis.
Tips: Enter kinetic energy in Joules and mass in kilograms. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What are the SI units for this formula?
A: The formula uses standard SI units: meters per second (m/s) for velocity, Joules (J) for kinetic energy, and kilograms (kg) for mass.
Q2: Can this formula be used for relativistic speeds?
A: No, this formula is derived from classical mechanics and is not valid for objects moving at relativistic speeds approaching the speed of light.
Q3: What if the mass is zero?
A: Mass cannot be zero in this calculation as it would result in division by zero, which is mathematically undefined.
Q4: How does velocity change with increasing kinetic energy?
A: Velocity increases with the square root of kinetic energy when mass is constant. Doubling the kinetic energy increases velocity by a factor of √2 (about 1.414).
Q5: What are practical applications of this formula?
A: This formula is used in various fields including ballistics, vehicle safety testing, sports science, and any application involving the conversion between kinetic energy and velocity.
