From: | To: |
The momentum to mass formula calculates the mass of an object when its momentum and velocity are known. This is derived from the fundamental physics equation p = m × v, rearranged to solve for mass.
The calculator uses the mass formula:
Where:
Explanation: The formula demonstrates the direct relationship between momentum and mass, with velocity as the determining factor in their proportionality.
Details: Calculating mass from momentum is essential in physics applications, particularly in mechanics and dynamics problems where momentum is known but mass needs to be determined for further analysis.
Tips: Enter momentum in kg·m/s and velocity in m/s. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is momentum in physics?
A: Momentum is a vector quantity that represents the product of an object's mass and its velocity (p = m × v).
Q2: Why can't velocity be zero in this calculation?
A: Velocity cannot be zero because division by zero is mathematically undefined. An object with zero velocity has zero momentum regardless of its mass.
Q3: What are the SI units for this calculation?
A: Momentum is measured in kg·m/s, velocity in m/s, and the resulting mass is in kilograms (kg).
Q4: Can this formula be used for relativistic speeds?
A: No, this formula uses classical mechanics. For relativistic speeds approaching the speed of light, the relativistic momentum formula must be used.
Q5: How is this calculation applied in real-world scenarios?
A: This calculation is used in collision analysis, rocket propulsion calculations, and various engineering applications where momentum is measured but mass needs to be determined.
