Energy in a rocket launch
Transcript of Energy in a rocket launch
Before the rocket launched, potential energy was stored in the battery and the engine of the rocket.
The chemicals in the engine of the rocket get fired up and cause the rocket to launch.
The chemical energy from the engine transforms into light energy, sound energy and kinetic energy. The rocket launches and sparks come out of the exhaust, making a hissing sound.
The gravitational pull stops the rocket from going up so the rocket starts falling down.
Energy in a rocket launch
The electrical energy fires up the chemicals in the engine.
When the rocket reaches its highest point, the kinetic energy has transformed into gravitational energy as the rocket is now high above the ground.
At the top of the rockets flight, it releases its parachute, which creates a sound.
When the rocket hits the ground, sound energy is released.
Kinetic -> SOUND ENERGY
Gravitational energy -> KINETIC ENERGY
Kinetic Energy -> GRAVITATIONAL ENERGY
Chemical energy -> LIGHT ENERGY/SOUND ENERGY/KINETIC ENERGY
Electrical energy -> CHEMICAL ENERGY
Potential energy -> ELECTRICAL ENERGY
Definitions of energy types
Potential energy is the stored energy of position possessed by an object. An object can store energy as the result of its position. This stored energy of position is referred to as potential energy. A drawn bow is able to store energy as the result of its position. When assuming its usual position (when not drawn), there is no energy stored in the bow. Yet when its position is altered from its usual position, the bow is able to store energy because of its position. Other examples of potential energy are fuels, springs, elastics, etc.
Electrical energy is energy that is caused by moving electric charges. Since the electric charges are moving, this is a form of kinetic energy. The faster the electric charges are moving the more electrical energy they carry
Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by-product. Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.
The kinetic energy of an object is the energy that it has due to its motion. It is defined as the work needed to accelerate an object of a certain mass from rest to its stated velocity. Having gained this energy during its acceleration, the object maintains this kinetic energy unless its speed changes. The same amount of work is done by the object in slowing down from its current state to a state of rest.
Light consists of photons, which are essentially tiny packets of energy. When an object's atoms heat up, this results in the production of photons and is how photon production occurs in most cases. The electrons in atoms find excitement from the heat, which results in them earning extra energy. The release of this energy is in the form of a photon, and more photons come out as the object gets hotter. When light travels, it is in the form of a wave. However, no material or matter is necessary to carry the energy along for the ride. Because of this, light can travel through a space that has no air.
Sound energy is a form of energy that is associated with vibrations of matter. It is a type of mechanical wave which means it requires an object to travel through. This object includes air and water. Sound originates from the vibrations that result after an object applies a force to another object.
Gravitational energy is the potential energy held by an object because of its high position compared to a lower position. In other words, it is energy associated with gravity or gravitational force. For example, a pencil being held above a table has a higher gravitational potential than a pencil sitting on the table
