Why does the pendulum not go as high when it swings back Where does lost potential energy go?

Most of it gets lost as friction.


A swinging pendulum demonstrates which type of energy?

A swinging pendulum demonstrates primarily two types of energy - kinetic energy when the pendulum is in motion, and potential energy - based on how high it is above the mid-point of the swing. If not for friction, a pendulum would continue to swing forever, with the sum of the kinetic and potential energy remaining constant but the distribution between the two constantly changing as the pendulum moved through its swings.


Is the ending and starting height of the pendulum exactly the same?

No, the swing of the pendulum will never carry it back quite as high as it was when it started. The pendulum must work against air resistance, and so a little bit of momentum is lost with every swing. Even if the pendulum operated in a vacuum, there would still be some tiny amount of friction at the point where the pendulum is attached to its frame. The swing of a pendulum is never 100% efficient. So the pendulum will run down.


Which questions would be answered using concepts from physics?

What are the forces that cause a pendulum to swing? How high will a thrown object rise before gravity pulls it back to Earth?


What does a pendulum have to do with potential and kinetic energy?

There are 3 Points at which the pendulum significantly changes direction. First it starts off pulled back before it is released it has a high potential energy because it is higher from the source of gravitation (generally the earth) but has no kinetic energy because it is not moving. Once released the pendulum loses potential energy and it swings downward and gains kinetic energy as it speed up. At the bottom of its swing it is going as fast as it will and has the highest kinetic energy and the lowest potential energy, then as it rises it loses the kinetic energy because it has to fight against gravity and loses kinetic energy and gains potential energy as it rises. And it repeats itself. One important thing to note is this is a great application of the law of conservation of energy because as it loses potential energy it gains the same energy in kinetic energy and vice versa (not counting the effects of wind resistance and friction however minor).

What is VHF Osilator?

A VHF ocsillator is a very high frequency ocsillator (30-300MHz). It oscillates (swings back and forth) at a VHF frequency.

Why do you have mood swings when you get your period?

Because your hormone levels are high!


What is special about pendulum swing?

No matter how high you set a pendulum, the amount of time for it to take one arc (maximum to maximum) will always remain the same.

What happens when a gun fires?

The bullet is pushed out of the barel at high speed by expanding gasses from the burning gunpowder. At the same time, the gun is pushed back by the recoil. This is the "equal and opposite reaction" mentioned in the Laws of motion.


How would the period of the simple pendulum be change if the pendulum is moved from the sea level to the top of the high mountain?

It's faster at sea level and slower at the top of a mountain.


Why does a pendulum lose time in summer and gain in winter?

Time period of pendulum is, T= 2π*SQRT(L/g) In summer due to high temperature value of 'l' increases which increases the time period of pendulum clock. Hence, pendulum clock loses time in summer. In winter due to low temperature value of 'l' decreases which decreases the time period of pendulum clock. Hence, pendulum clock gains time in winter.
