Momentum, change in momentum, and impulse
Momentum, change in momentum, and impulse
Momentum is the product of mass and velocity, so it depends on both size and direction. The formula is
p=mv p = mv p=mvand the unit is kg m s−1\text{kg m s}^{-1}kg m s−1.
Step-by-step lessons on Edexcel A Level Physics Impulse and two-dimensional momentum. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
