Formula
J = Fฮt = ฮp = m(vโ-vโ)
Impulse equals the change in momentum. Longer contact time reduces peak force.
Worked Examples
Example 1: Baseball hit
Problem:0.145 kg ball, 0โ40 m/s in 0.001s
Solution:J=0.145ร40=5.8 Nยทs, F=5800 N
Result:5800 N average force
Frequently Asked Questions
What is momentum and how is it conserved?
Momentum is p = mv (mass times velocity). In a closed system with no external forces, total momentum is conserved. In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved but kinetic energy is not. Impulse (F*t) equals the change in momentum.
