Edexcel International GCSE Physics 1c Forces, movement, shape and momentum checklist

Paper 2 only

Know and use the relationship between momentum, mass and velocity: momentum = mass × velocity; p = m × v
Use the idea of momentum to explain safety features
Use the conservation of momentum to calculate the mass, velocity or momentum of objects
Use the relationship between force, change in momentum and time taken: force = change in momentum / time taken; F = (mv − mu) / t
Demonstrate an understanding of Newton’s third law
Know and use the relationship between the moment of a force and its perpendicular distance from the pivot: moment = force × perpendicular distance from the pivot
Know that the weight of a body acts through its centre of gravity
Use the principle of moments for a simple system of parallel forces acting in one plane
Understand how the upward forces on a light beam, supported at its ends, vary with the position of a heavy object placed on the beam
