Energy Dynamics in Rocketry

What is the primary type of energy stored in a rocket's fuel before launch?

• Kinetic Energy

• Chemical Potential Energy

• Gravitational Potential Energy

• Thermal Energy

Which of the following best describes the energy conversion that occurs when a rocket is launched?

• Gravitational potential energy to kinetic energy

• Chemical potential energy to kinetic energy

• Kinetic energy to thermal energy

• Thermal energy to gravitational potential energy

Which formula represents the kinetic energy of a rocket in motion?

Explain why a rocket gains kinetic energy as it ascends.

• Because it loses mass

• Because it converts chemical energy into kinetic energy

• Because it gains gravitational potential energy

• Because it moves faster

What happens to the gravitational potential energy of a rocket as it moves further from Earth?

• It decreases

• It remains constant

• It increases

• It becomes zero

A rocket is launched vertically upwards. Describe the energy transformation that occurs as it reaches its maximum height.

• Kinetic energy is transformed into gravitational potential energy

• Gravitational potential energy is transformed into kinetic energy

• Chemical energy is transformed into thermal energy

• Thermal energy is transformed into kinetic energy

If a rocket's speed doubles, how does its kinetic energy change?

• It remains the same

• It doubles

• It quadruples

• It halves

Discuss the role of gravitational potential energy in the context of a rocket's launch and ascent.

• It is irrelevant to the rocket's motion

• It decreases as the rocket ascends

• It provides the energy needed for the rocket to reach space

• It increases as the rocket ascends, storing energy

A rocket has a mass of 2000 kg and is moving at a velocity of 300 m/s. Calculate its kinetic energy.
