Momentum, Impulse and Car Safety | IGCSE Physics | Cambridge 0625 · Edexcel 4PH1 · OxfordAQA 9203

Momentum, impulse and vehicle safety for IGCSE Physics: p = mv, momentum as a vector, force as the rate of change of momentum (F = Δp/Δt and F = (mv − mu)/t), impulse, how crumple zones, seat belts and air bags reduce the force, conservation of momentum in collisions and explosions, and Newton's third law. 📝 Cambridge 0625 notes: Momentum (free): https://www.thinka.ai/en-GB/Cambridge... 📱 Thinka app: practice questions, flashcards and notes: https://www.thinka.ai/en-GB/download?...
