Work Energy And Impulse Momentum Principles Conservation Of Momentum
Work Energy and Impulse Momentum Principles - Concepts to Remember
Work and Energy
- Energy Forms: Kinetic, potential (gravitational, elastic), internal, mechanical, thermal energies, etc.
- Work-energy Theorem: Work done = change in kinetic energy.
- Potential Energy: Dependence on position/configuration.
- Conservative/Non-conservative Forces: Work dependence on path.
- Conservation of Energy: Total energy constant in isolated systems.
Impulse and Momentum
- Impulse-momentum Theorem: Net impulse = change in momentum.
- Momentum Vector Quantity: Magnitude and direction matter.
- Conservation of Momentum: Total momentum constant (no external forces).
Collisions
- Collision Types: Perfectly elastic, inelastic, completely inelastic.
- Momentum/Energy Conservation: In elastic and inelastic collisions.
- Coefficient of Restitution: Measures collision elasticity.
Applications
- Forces, Work, Energy, Momentum Calculations: Mechanical systems and scenarios.
- Real-Life Situations: Collision analysis in sports, transport, engineering.
