How is energy conserved in a roller coaster?
When it is going down, they reduce the power on the track because it is already going fast enough. This uses less energy.
How is energy conserved when a car slows down?
Objects use more energy when increasing in speed or starting while objects use less energy while going at a steady pace.
What brakes sugar down to produce energy?
It is a organ
Examples of the law of conservationof energy?
Since energy is ALWAYS conserved, anything that happens is an "example". For example, an object just sitting around. However, it is usually more interesting to analyze what happens when one type of energy is converted to another. For example, if a car brakes, the car's kinetic energy is converted to heat (in the brakes); when you throw an object up, kinetic energy is converted to potential energy; when it falls back down, the potential energy is converted back to kinetic energy; and if in this example there is air resistance, part of the kinetic energywill be converted to heat.
What is true about the total energy of a ball as it rolls down a hillside?
It is conserved. The potential energy of the ball sitting at the top of the hill is converted into kinetic energy of the rolling ball.
How can energy be conserved as a skater rolls down a ramp?
When rolling down, potential energy is converted into kinetic energy. If there is no friction, this means the skater moves faster and faster. If there is energy (the usual situation), part of this movement energy (kinetic energy) will be converted into heat.
Why should car brakes be checked regularly?
You wouldn't want to be going down an incline (a hill) and find you have no brakes!
When a vehicle is slowing down what changes its momentum and kinetic energy as force of brakes is an internal force?
Brakes absorb the kinetic energy in the form of heat and sometimes sound. When hot enough brakes can emit light.
How is energy transformed as you ride a roller coaster?
Potential energy and Kinetic Energy are interchanged many times as the cars slow down going up the hills, and speed up going down the hills. At the very end of the ride Kinetic Energy is turned into Thermal Energy (Heat) as the brakes stop the motion of the cars.
Can you give me a science trivia about matter and energy?
Energy cannot be made or destroyed only changed from one energy to another. e.g in a car when you are moving you are producing kinetic energy but when you apply the brakes to slow down you are changing the kinetic energy to heat energy through the brakes.
What bacteria can break down ammonia into a gaseous form of nitrogen?

What is down conversion?
Down conversion is a word related to physics, it is simply a concept of the interaction of a photon and a medium which is used to convert two photons of lower frequencies such that energy is conserved.
