Momentum کا حساب کیسے لگائیں

Momentum کیا ہے؟

Momentum is the product of mass and velocity, while impulse is the change in momentum caused by a force over time. Together they describe how objects change motion.

فارمولا

The calculator finds momentum (p = m × v) and impulse (J = F × Δt = Δp)

J: F × Δt = Δp) — F × Δt = Δp)
F: Δp) — Δp)
p: m × v) and impulse (J = F × Δt = Δp) — m × v) and impulse (J = F × Δt = Δp)

مرحلہ وار گائیڈ

1Enter initial velocity, final velocity, mass, or force and time duration
2The calculator finds momentum (p = m × v) and impulse (J = F × Δt = Δp)
3Results show both values and verify the impulse-momentum relationship

حل شدہ مثالیں

ان پٹ

m = 2 kg, v₀ = 5 m/s, v_f = 15 m/s

نتیجہ

Δp = 20 kg·m/s

Or F × t = 20 N·s for any force duration

عام غلطیاں جن سے بچنا ہے

✕Confusing momentum direction with speed magnitude
✕Applying conservation incorrectly in systems with friction or air resistance

اکثر پوچھے جانے والے سوالات

Why is impulse important in collisions?

Extending the collision time (increasing Δt) reduces the force needed, which is why airbags save lives.

Is momentum conserved?

Yes, in isolated systems with no external forces. This is why collisions between objects follow predictable patterns.
