Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
Q. Why does a glass filled with water smash when you run your finger along the rim of the glass? Answer:- A portion of crystal stemware has a natural or resonant frequency
why friction is called a necessery evil?
In whole analog to the work energy theorem for the translator motion, it might be stated for rotational motion as: Δ W rot = K rot The net rotational work given by the force
Magnetism: 1. There are two types of magnetic pole north and south. 2. Like poles repel and unlike pole attract each other. 3. Magnetic substance produce magnetic field.
Describe the magnetic moment of a bar magnet. What is its direction? Can you find two magnetic field lines intersecting? Why?
What is the Principal value branch of i i Ans) Principal value branch of ii=e-π/2
To determine the acceleration due to gravity using a simple pendulum. Apparatus: Pendulum, meter scale, stand, stop watch, vernier callipers. Procedure: 1. The diameter of the bob
is there relation between emf and size os cell?
How do you magnetize metal? You can rub a magnet with the metal in single direction for a bunch of times (the more the better), and that will magnetize it to some degree, but i
