Mass Formula:
From: | To: |
The mass calculation formula \( m = \frac{F \times t}{\Delta v} \) is derived from the impulse-momentum theorem, which states that the impulse of a force equals the change in momentum of an object.
The calculator uses the formula:
Where:
Explanation: This formula calculates the mass of an object by relating the impulse (force × time) to the change in momentum (mass × velocity change).
Details: Calculating mass from force and time measurements is important in physics experiments, engineering applications, and understanding the relationship between force, motion, and mass in various systems.
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 greater than zero.
Q1: What is the impulse-momentum theorem?
A: The impulse-momentum theorem states that the impulse of a force acting on an object equals the change in momentum of that object (J = F × t = m × Δv).
Q2: When is this formula applicable?
A: This formula is applicable when a constant force is applied to an object for a specific time period, resulting in a change in velocity.
Q3: What are the units of measurement?
A: Force in newtons (N), time in seconds (s), velocity change in meters per second (m/s), and mass in kilograms (kg).
Q4: Can this formula be used for variable forces?
A: For variable forces, the calculation requires integration of force over time, making it more complex than this simple formula.
Q5: What are practical applications of this calculation?
A: This calculation is used in crash testing, sports science, rocket propulsion, and any scenario where force application time and velocity change can be measured to determine mass.
