Question
part a
which of the following best explains what happens to
a the rocket gains energy as it rises because it
b energy is transformed from one form to another, but the total amount stays the same.
c the rocket uses up all its energy at the peak of its flight
d energy is lost as the rocket moves through the air
part b
using the information provided to the left, match the stage of the rockets motion with the main forms of energy present at that time by clicking where the correct columns and rows meet up
kinetic + gravitational potential energy chemical energy mostly gravitational potential energy kinetic + heat
at launch
rising through the air
at peak height
at landing
part c
- Part A: Según la ley de conservación de la energía, la energía no se crea ni se destruye, solo se transforma de una forma a otra. Cuando un cohete vuela, la energía se transforma, pero la cantidad total de energía permanece constante.
- Part B:
- Al lanzamiento: El cohete tiene energía química almacenada en su combustible.
- Subiendo por el aire: Tiene energía cinética por su movimiento y energía potencial gravitacional por su altura.
- En la altura máxima: Tiene principalmente energía potencial gravitacional ya que su velocidad momentánea es cero.
- Al aterrizar: Tiene energía cinética y también se produce calor debido a la fricción con el aire y al impacto.

- Part A: B. Energy is transformed from one form to another, but the total amount stays the same.
- Part B:
- At launch: Chemical Energy
- Rising through the air: Kinetic + Gravitational Potential energy
- At peak height: Mostly Gravitational Potential energy
- At landing: Kinetic + Heat
