Front

Which of the following options best explains the energy transformation that occurs when a car's engine heats up while driving?

Back

Kinetic energy is converted into thermal energy due to friction and fuel combustion.

A charged balloon is placed near a wall. It remains attracted to the wall without moving. What type of energy is this an example of?

Back

Electric potential energy

Front

What is the main reason for the change in speed of a planet as it orbits the Sun, according to Kepler's Second Law?

Back

The distance between the planet and the Sun changes.

Front

A moon orbits a planet. If the mass of the planet were to increase significantly while the distance between them remained unchanged, what would happen to the gravitational force acting on the moon?

Back

It would increase.

Front

A comet orbits the Sun in a highly elliptical path. As the comet approaches the perihelion (the closest point to the Sun), what can be said about its speed?

Back

Its speed increases.
