Motion and Momentum
This final page focuses on various types of motion and the concept of momentum, providing formulas and relationships for different scenarios.
Definition: Quantità di moto momentum is defined as the product of mass and velocity: p = mv
The page presents formulas for different types of motion:
- Uniformly accelerated motion: s = v₀t + 1/2 at²
- Free fall: v² = 2gh
- Projectile motion: Range = v02sin2θ/g
Highlight: The teorema dell'impulso states that the change in momentum equals the impulse: Δp = F · Δt
The conservation of momentum is illustrated for collisions:
Example: In a collision between two objects, m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂', where primed velocities are after collision.
The page also includes formulas for accelerated and decelerated motion, as well as two-dimensional motion.
Vocabulary: Moto circolare uniformemente accelerato refers to circular motion with constant angular acceleration.
Lastly, the page provides trigonometric relationships for solving problems involving triangles in physics contexts.
