Unit 4 Linear Momentum
- 4.1 Linear Momentum
Linear momentum, p⃗ · Momentum as a vector · Collisions and explosions described by momentum
- 4.2 Change in Momentum and Impulse
Net external force as rate of change of momentum · Impulse, J⃗ · Direction of impulse · Impulse from a force–time graph · Net force from a momentum–time graph · Change in momentum, Δp⃗ · Impulse–momentum theorem
- 4.3 Conservation of Linear Momentum
System · Total momentum of a system, p⃗sys · Internal and external forces · Conservation of momentum in collisions and explosions · Momentum transfer · Constant total momentum · Momentum exchange with the environment
- 4.4 Elastic and Inelastic Collisions
Kinetic energy of a system · Transfer of kinetic energy in an elastic collision · Inelastic collision · Transformation by nonconservative forces · Perfectly inelastic collision
