FLASHCARD QUESTION
Front
What is kinetic energy?
Back
Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

FLASHCARD QUESTION
Front
How is potential energy converted to kinetic energy?
Back
Potential energy can be converted to kinetic energy when an object moves. For example, when a roller coaster descends from a height, its potential energy decreases while its kinetic energy increases.

FLASHCARD QUESTION
Front
What is the formula for kinetic energy?
Back
The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

FLASHCARD QUESTION
Front
What happens to energy in a closed system?
Back
In a closed system, energy is conserved. It can change forms (e.g., from potential to kinetic) but the total energy remains constant.
