Momentum and Impulse notes

This section is linear momentum and change in momentum. The exam wants the official definition, $p=mv$, SI unit, the vector nature (same direction as velocity), and **$\Delta p=p_f-p_i$as a vector, including…

This section is Newton's second law in terms of momentum and impulse. The exam wants the official statement, $F_{\mathrm{net}}=\Delta p/\Delta t$, the link between net force and **$\Delta p$, impulse** $=F_{\mathrm{net}}\Delta t$, and the impulse…

This section is the principle of conservation of linear momentum. The exam wants a system, internal vs external forces, an isolated/closed system ($F_{\mathrm{net, ext}}=0$), the official statement, and…

This section is collision types and one-dimensional problem-solving. Elastic versus inelastic is a kinetic-energy test. Linear momentum is conserved in both, if the system is isolated. Perfectly…

Momentum and impulse are fundamental concepts in mechanics that help us analyse collisions and the effects of forces over time. This topic extends Newton's laws to provide powerful tools for solving…
