🎱 Momentum Calculator
Calculate momentum and impulse
Momentum: p = mv
Impulse: J = FΔt
How Momentum Calculation Works
Formula
p = m × v; J = F × Δt = Δp
- 1Enter mass (kg) and velocity (m/s) to calculate momentum.
- 2Momentum = mass × velocity, measured in kg·m/s.
- 3Optionally enter force and time interval for impulse.
- 4Impulse equals force times time interval (J = FΔt).
- 5The impulse-momentum theorem states J = Δp (impulse equals change in momentum).
About Momentum Calculator
Calculate momentum (p = mv) and impulse (J = FΔt). Enter mass and velocity for momentum, or force and time for impulse calculation.
Frequently Asked Questions
What is momentum?
Momentum is the product of mass and velocity (p = mv). It's a vector quantity that describes how hard it is to stop a moving object. A heavy truck and a fast bullet can have similar momentum.
What is the impulse-momentum theorem?
The impulse-momentum theorem states that impulse (J = FΔt) equals the change in momentum (Δp). This explains why airbags work — they increase the time of collision, reducing the force.
Is momentum always conserved?
In a closed system with no external forces, total momentum is always conserved. This applies to all collisions — elastic (bouncing) and inelastic (sticking together).
