Multiple Choice QuestionWhen a planet is in orbit close to the sun, its PE is Blank______ and its KE is Blank______, and when a planet is far from the sun, its PE is Blank______ and its KE Blank______.Multiple choice question.low; high; higher; lowerhigh; low; lower; higher
Solution
The correct answer is "low; high; higher; lower".
Here's why:
-
Potential Energy (PE): This is energy an object has due to its position relative to other objects. In this case, when a planet is close to the sun, it is at the bottom of the gravitational well, so its potential energy is low. When the planet is far from the sun, it is higher in the gravitational well, so its potential energy is higher.
-
Kinetic Energy (KE): This is energy an object has due to its motion. When a planet is close to the sun, it moves faster due to the stronger gravitational pull, so its kinetic energy is high. When the planet is far from the sun, it moves slower due to the weaker gravitational pull, so its kinetic energy is lower.
