Question
Where does the ball get it’s kinetic energy from? Where does the source get its energy from? Trace the energy in this experiment step by step back to its source in the core of the sun. Where did the rest of the ball’s energy go?
8. Energy and Momentum Conservation The principles of momentum conservation in a collision and energy conservation in a swinging pendulam are used to determine the mechanical energy lost in a "totally inelastic collision. Apparatus A metal ball, a spring loaded gun, a pendulum with a hollow chamber with a ratchet mechanism to trap the ball, a scale and a meter stick. Physical Principles In this lab a metal ball collides with a plastic chamber at the end of a hanging pendulum. The collision is called "totally inelastic," because the two objects move as one after the collision, thanks to a ratchet mechanism in the chamber. The mechanism traps the ball, preventing it from "elastically" bouncing off the back of the chamber. Three moments of interest must be considered in this process: 1- when the ball is flying towards the pendulum 2 -immediately after the ball's collision with the pendulum 3 - when the pendulum reaches its maximum height The principle of momentum conservation will be used to relate moments 1 and 2, and the principle of mechanical energy conservation will be used to relate moments 2 and 3. The principle of momentum conservation states that the total momentum before the collision is equal to the total momentum after the collision. Since the chamber has no momentum before the collision, this means that the ball's momentum before the collision is equal to the pendulum's momentum just after the collision: where mo represents the mass of the ball, m, represents the mass of the pendulum with the ball in its chamber, vi represents the velocity of the ball just before the collision, and represents the initial velocity of the pendulum's center of mass just after the collision.Explanation / Answer
the ball got its kinetic energy from the mechanical appratus installed at the beginning of the experimental appratus
the source for the enrgy of this mechanical appratus is probably electronic
the electrical power used for converting the electrical energy into mechanical was sourced from a coal power plant
the potential combustible energy in the coal cam efrom the organic plants that decayed to make it
the organic plants got theor energy from the sun
the rest of the energy of the ball was wasterd into the environment in the form of sound energy and heat energy
