Momentum and Impulse Calculator
Compute momentum, impulse, or force using p = m·v and J = F·Δt. Supports SI and common units for mass, velocity, force, and time.
momentum change calculator:
This Momentum and Impulse Calculator can be used to determine the linear momentum, impulse, velocity, or force. Get the calculator and enter any combination of two known quantities: mass, force, velocity, or time to use p = m⋅v and J = F⋅Δt to determine the unknown. Some of the outputs are step-by-step formulas, unit conversions, and the determination of momentum change during collisions or applied impulses.
Momentum and Impulse tool Formula:
The Momentum and Impulse Calculator enables you to solve the equations of momentum (p), impulse (J), force (F), or velocity (v) under the definition of Newton and the impulse-momentum law. p = m⋅v, where p is momentum, m is mass, and v is velocity. Impulse is J = F⋅Δt, which is the product of the force and the time interval over which the force acts. A calculator has the capability to solve any unknown given two variables. Users are able to determine the change in momentum ( Δp ) in collisions, the force needed to create a specific impulse, or the post-impulse velocity of a mass. The tool has SI units: mass in kg, velocity in m/s, force in N, impulse in N s, and time in seconds. It can be used by physics students, physics instructors, lab workers, and engineers who study linear movement or collision. Procedural solutions are shown step-by-step, and optional unit conversions and printable solutions are provided.
⚡ Work & Installation Input to Output:
Input: User provides any two of the following: mass (m), velocity (v), momentum (p), impulse (J), force (F), or time interval (Δt). User selects SI or common units.
Processing:
- Convert all inputs to SI units.
- Apply formulas algebraically:
- Momentum: p = m·v → m = p/v, v = p/m
- Impulse: J = F·Δt → F = J/Δt, Δt = J/F
- Impulse-momentum theorem: J = Δp → Δv = J/m
- Validate inputs (e.g., no zero mass when computing velocity).
Output:
- Numeric results in SI units (kg·m/s, N·s, N, m/s).
- Step-by-step substitution for clarity.
- Derived quantities such as Δp or velocity after impulse.
- Optional printable summary or CSV export.
Testing and Final Adjustments
Test representative scenarios:
- Mass = 2 kg, v = 3 m/s → p = 6 kg·m/s
- Force = 10 N applied for 5 s → J = 50 N·s
- Impulse applied to 3 kg mass → Δv = J / m
- Momentum change during collisions: p_i = 4 kg·m/s, p_f = 7 kg·m/s → Δp = 3 kg·m/s
Check unit conversions (N·s ↔ kg·m/s, m/s ↔ km/h), edge cases (mass = 0), and step-by-step solution clarity. Validate UX: numeric keypad for mobile, labels for m, v, F, J, Δt, error messages for missing or invalid inputs. Add example presets for collisions, impulses, and moving objects. Ensure printable results work and SEO metadata includes “Momentum and Impulse Calculator,” “p = m·v,” “J = F·Δt,” and schema markup for calculators.
