Discuss the design of the roller coaster shown in the sketch in terms of the conservation of energy.?

The design is impractical. Note that the summit of each hill on the roller coaster is the same height, so the PE of the car at the top of each hill would be the same. If no energy were spent in overcoming friction, the car would get to the second summit with as much energy as it starts with. But in practice, there is considerable friction, and the car would not roll to its initial height and have the same energy. So the maximum height of succeeding summits should be lower to compensate for friction.

Can I build a roller coaster that shows Newton's Three Laws of Motion energy transformation transfer of energy and conservation of energy?
Every roller coaster demonstrates all of those. The challenge is not in how to build it.The challenge is in how to watch it run and identify each of those principles in action.
How does the law of conservation-of energy relate to roller coasters?
It is easier to see this using a traditional roller coaster model. Most traditional Roller Coasters start by using a tow cable to pull them up a large "hill". When being pulled up this hill, mechanical energy is being used to give the roller coaster potential energy. At the top of this hill, the roller coaster has it's maximum potential energy. As it starts to go down another hill, it picks up speed. During the descent it is losing potential energy but at the same time gaining kinetic energy. The coaster will then lose kinetic energy but gain potential energy as it goes up the next hill. This cycle of gaining/losing potential and kinetic energy is the conservation of energy that you are looking for. Of course in a real roller coaster, some energy will be lost due to friction. This will come off as heat in the rails and the wheels of the roller coaster and it's structure.

How is energy transferred from potential to kinetic on a roller coaster?
Energy is transferred from potential to kinetic on a roller coaster as the coaster descends from a higher elevation to a lower elevation. As the coaster moves downwards, gravitational potential energy is converted into kinetic energy. This energy transfer allows the coaster to gain speed and momentum.
What are 5 energy conversions in a roller coaster?
Potential energy to kinetic energy: at the top of a hill, the coaster has high potential energy which is converted to kinetic energy as it speeds down the hill. Kinetic energy to potential energy: as the coaster climbs up a hill, its kinetic energy decreases and is converted back to potential energy. Mechanical energy to thermal energy: friction between the coaster and the track converts mechanical energy into thermal energy, causing the coaster and track to heat up. Electrical energy to kinetic energy: in a launched coaster, electrical energy is converted to kinetic energy as the coaster accelerates along the track. Potential energy to sound energy: when the coaster goes over bumps or loops, potential energy is converted to sound energy as the coaster vibrates and creates noise.
How does chemical energy work on a rollercoaster?
Chemical energy in a rollercoaster comes from the potential energy stored in the coaster's initial position which is converted to kinetic energy as the coaster moves downhill. This conversion is due to the force of gravity acting on the coaster. The kinetic energy propels the coaster along the track, and as the coaster climbs uphill, some of this kinetic energy is converted back to potential energy.
When does a roller coaster increase kinetic energy?
A roller coaster increases kinetic energy when it is going downhill, as gravity is pulling it down and accelerating it. The potential energy is converted into kinetic energy as the roller coaster gains speed.
On a Roller Coaster where is the potential energy?
When the roller coaster is at its highest position and is not moving then its potential energy is highest
Where is potential energy on a roller coaster?
When the roller coaster is at its highest position and is not moving then its potential energy is highest
What energy conservation takes place when a flashlight is turned on?
When a flashlight is turned on, energy conservation occurs because the electrical energy from the batteries is converted into light energy without significant losses. The flashlight's design ensures that minimal energy is wasted as heat or other forms of energy, allowing most of the energy input to be efficiently utilized for producing light.
