Work, Energy, and Conservation Laws

This page delves into the concepts of work, energy, and conservation laws, providing key formulas and relationships.

Definition: Work is defined as the product of force and displacement in the direction of the force: W = F · s · cos θ

The page presents formulas for various forms of energy:

  • Kinetic energy: E_c = 1/2 mv²
  • Potential energy (gravitational): U = mgh
  • Elastic potential energy: U = 1/2 kx²

Highlight: The principio di conservazione dell'energia meccanica formula states that the total mechanical energy (kinetic + potential) remains constant in a closed system: E_initial = E_final

The work-energy theorem is presented, relating work done to change in kinetic energy: W = ΔE_c

Vocabulary: Impulso (impulse) is defined as the product of force and time interval: I = F · Δt

The page also covers concepts in Galilean relativity and gravity, including Newton's law of universal gravitation.

Example: The gravitational force between two masses m₁ and m₂ is given by F = G(m₁m₂)/r², where G is the gravitational constant.

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 = (v₀² sin 2θ)/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.

Circular Motion and Conservation Laws

This page introduces fundamental concepts in circular motion and provides essential formulas for uniform circular motion and motion on inclined planes.

Definition: Moto circolare uniforme refers to uniform circular motion, where an object moves in a circular path at constant speed.

Key formulas for uniform circular motion include:

  • Period (T) and frequency (f) relationship: T = 1/f
  • Angular velocity (ω): ω = 2π/T = 2πf
  • Tangential velocity (v): v = ωR, where R is the radius
  • Centripetal acceleration (a_c): a_c = v²/R = ω²R

Highlight: The formula periodo moto circolare (period of circular motion) is T = 2π/ω, which relates the period to angular velocity.

For motion on an inclined plane, the page presents formulas for both smooth and rough surfaces, considering components of weight parallel and perpendicular to the plane.

Example: For a smooth inclined plane, the acceleration down the plane is given by a = g sin θ, where θ is the angle of inclination.

The page also includes formulas for velocity and displacement in various scenarios, such as objects sliding down inclined planes or projectile motion.
