What happens to energy that seems to be lost in an energy chain?
Energy is NEVER lost in an energy chain. It is simply converted into a different source of energy or matter. For example, in swing, a person would get on, and use mechanical energy to power it so it can move. What people don't realize is that on the top, the metal chains that hold the swing together also moves along with the swing. Up there, the mechanical energy that moves the chains a little, and friction starts to occur. But that's not it. Instead of helping with the movement below, frictional force above the swing causes energy to be somehow "lost" in the trail. That's not true at all. The energy "lost" is converted into heat in the process.
Jill is getting ready to push little Frank in his swing She pulls Frank back as high as she can and then releases the swing What is the initial transfer of energy that accelerates the swing when s?
Potential energy mostly transferring to kinetic energy (some of the energy will also dissipate as heat from friction - air friction, friction where the ends of the chain or rope is rubbing against whatever it is attached to, etc.) The potential energy comes from Jill raising Frank in the gravitational field of the earth.
How is energy converted as a pendulum swing?
From potential to kinetic and back again - with every swing.
Is in a pendulum at the top of a swing chemical energy?
No, it is not a chemical form of energy.
If the potential energy of a swing is 200 J at its highest point and 50 J at its lowest point what is the kinetic energy of the swing at its lowest point if mechanical energy is conserved?
150J, as the potential energy has been converted to kinetic energy as the swing accelerates downwards (and forwards) from the top of its swing. Therefore the decrease in potential energy corresponds directly to the increase in kinetic energy if we are ignoring things like friction. So KE = 200-50= 150
Why a simple pendulum will not swing continuously in air?
Because of the air resistance which causes the pendulum to gradually lose energy.
Explain how the maximum height is related to the maximum potential energy?
This question makes sense in the context of something like a pendulum. At the top of its swing, a pendulum is at maximum height, is not moving and so has zero kinetic energy, and has maximum potential energy since all its energy is potential. As it falls, it gradually moves with increasing speed, so its potential energy is being converted to kinetic energy. At the bottom of the swing, it is moving at maximum speed, and all its energy is kinetic, none is potential, Then it starts to move upwards again, and its kinetic energy is gradually converted back to potential energy.
What do you do if a child is scared of swings?
You can just give them some time and let them get more mature. If it seems abnormal try introducing the swing gradually. First have them play near it. Then have them sit on it but not swing. Then gradually swing more and more. You can also have them start out in a baby swing or on your lap to get them used to it. Many will enjoy sitting on your lap as it feels safe.

How is energy transformed durning the period of a swing in a system such as a playground swing?
i thing that the energy cannot change
Jill is getting ready to push little Frank in his swing. She pulls Frank back as high as she can and then releases the swing. What is the initial transfer of energy that accelerates the swing when she?
Potential energy mostly transferring to kinetic energy (some of the energy will also dissipate as heat from friction - air friction, friction where the ends of the chain or rope is rubbing against whatever it is attached to, etc.) The potential energy comes from Jill raising Frank in the gravitational field of the earth.

'Swing swing from the tangles of your heart' comes from which song and what group?
those lyrics come from the song 'swing swing' by All American Rejects.
A certain pendulum has a potential energy of 20 J when it is at the top of its swing. What is the kinetic energy?
If at the top of the swing the pendulum is STOPPED then it has zero kinetic energy.
where on the swing is the kinetic energy the greatest and the potential energy the least?
In between the ground and the bar that holds the swing up so the middle
Is a riders highest point on a swing a potential energy or kinetic energy?
At the highest point it's potential energy, which is then completely converted to kinetic energy as the swing travels through its lowest point at maximum speed. With an ideal swing (no friction) the sum of potential and kinetic energy stays constant (it is 'conserved'). In practice it dies away as the swing slows down, but Conservation of Energy is an important principle in science.
How does Kinetic and Potential energy relate to Pendulums in different ways?
Maximum kinetic energy occurs at the bottom of the swing. Maximum potential energy occurs at the top of the swing.
