Mass Calculation Formula:
From: | To: |
The mass calculation from force and velocity uses the impulse-momentum theorem to determine an object's mass when force, time, and velocity change are known. This approach is derived from Newton's second law of motion.
The calculator uses the formula:
Where:
Explanation: This formula is derived from the impulse-momentum theorem, where impulse (F×t) equals the change in momentum (m×Δv).
Details: Calculating mass from force and velocity measurements is crucial in physics experiments, engineering applications, and motion analysis where direct mass measurement may not be feasible.
Tips: Enter force in newtons (N), time in seconds (s), and velocity change in meters per second (m/s). All values must be positive numbers.
Q1: What is the impulse-momentum theorem?
A: The impulse-momentum theorem states that the impulse applied to an object equals the change in its momentum (F×t = m×Δv).
Q2: When is this calculation most useful?
A: This calculation is particularly useful in collision analysis, rocket propulsion, and any scenario where force is applied over time to change an object's velocity.
Q3: What are the SI units for this calculation?
A: Force in newtons (N), time in seconds (s), velocity change in meters per second (m/s), and mass in kilograms (kg).
Q4: Are there limitations to this formula?
A: This formula assumes constant force and works best for rigid bodies where mass remains constant during the velocity change.
Q5: How does this relate to Newton's second law?
A: This is essentially a rearranged form of Newton's second law (F = m×a), where acceleration is expressed as Δv/t.
