Wahadło Sprężynowe: Energy Transformations and Motion
This page provides a detailed illustration of a wahadło sprężynowe springpendulum and its energy states throughout its oscillatory motion. The diagram shows the pendulum at various points in its swing, highlighting the changes in energy and forces acting upon it.
Definition: A spring pendulum is a mass attached to a spring that oscillates vertically, converting between potential and kinetic energy.
The illustration demonstrates how the przemiany energii w ruchu wahadła sprężynowego occur as it moves through different positions:
-
At the equilibrium position:
Kinetic energy Ek is at its maximum
Gravitational potential energy Epg and spring potential energy Eps are equal
The net force FN is zero
-
At the highest point:
Gravitational potential energy Epg is at its maximum
Kinetic energy Ek is zero
Spring force Fps is at its minimum
-
At the lowest point:
Spring potential energy Eps is at its maximum
Kinetic energy Ek is zero
Gravitational force Fg is at its maximum
Highlight: The total mechanical energy of the spring pendulum remains constant throughout its motion, in accordance with the zasada zachowania energii lawofconservationofenergy.
The diagram also includes important formulas related to the spring pendulum:
Vocabulary:
- Epg = mgh gravitationalpotentialenergy
- Eps = ½kx² springpotentialenergy
- Ek = ½mv² kineticenergy
- T = 2π√m/k okresdrganˊwahadłaspręz˙ynowegowzoˊr−periodofoscillation
These equations help in understanding the badanie wahadła sprężynowego and its behavior. The period of oscillation T depends on the mass m of the bob and the spring constant k, which is crucial for determining the częstotliwość drgań wzór frequencyofoscillation.
Example: As the mass m increases, the period of oscillation T also increases, meaning the pendulum swings more slowly.
The page concludes with notes on how different factors affect the pendulum's motion:
- Increasing kinetic energy Ek results in faster motion
- Higher gravitational potential energy Epg corresponds to a higher position of the weight
- Greater spring potential energy Eps indicates a more stretched spring
This comprehensive overview provides a solid foundation for understanding the przemiany energii w ruchu drgającym zadania energytransformationsinoscillatorymotionproblems and the fundamental principles governing the behavior of spring pendulums.
