Momentum Formula:
From: | To: |
Definition: This calculator computes the momentum of an object based on its mass and kinetic energy using the physics formula.
Purpose: It helps students, physicists, and engineers determine an object's momentum when its mass and kinetic energy are known.
The calculator uses the formula:
Where:
Explanation: The formula derives from the relationship between kinetic energy and momentum in classical mechanics.
Details: Momentum is a fundamental concept in physics that describes the quantity of motion an object has and is conserved in closed systems.
Tips: Enter the mass in kilograms and kinetic energy in joules. Both values must be positive numbers.
Q1: What are the units of momentum?
A: Momentum is measured in kilogram-meters per second (kg·m/s).
Q2: Can this formula be used for relativistic speeds?
A: No, this formula is for classical mechanics. For relativistic speeds, you need to use the relativistic momentum formula.
Q3: What's the relationship between momentum and kinetic energy?
A: Kinetic energy can be expressed in terms of momentum as \( E = \frac{p^2}{2m} \), which is why we can calculate momentum from energy.
Q4: Does this work for all types of energy?
A: No, this specifically calculates momentum from kinetic energy. Other forms of energy require different calculations.
Q5: What if my object has zero mass?
A: This formula doesn't apply to massless particles (like photons), which have momentum but no rest mass.
