FLASHCARD QUESTION
Front
What is kinetic energy?
Back
Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

FLASHCARD QUESTION
Front
What is potential energy?
Back
Potential energy is the stored energy of an object due to its position or state, commonly associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

FLASHCARD QUESTION
Front
At which point in a pendulum's swing is the potential energy the highest?
Back
The potential energy is highest at the highest points of the swing, where the pendulum momentarily comes to rest before swinging back down.

FLASHCARD QUESTION
Front
What happens to kinetic energy as a roller coaster descends a hill?
Back
As a roller coaster descends a hill, its potential energy decreases while its kinetic energy increases, resulting in higher speeds at the bottom.

FLASHCARD QUESTION
Front
What type of energy does a balloon filled with air possess?
Back
A balloon filled with air possesses potential energy due to the compressed air inside it.
6.
FLASHCARD QUESTION
Front
Where is potential energy greatest in a roller coaster?
Back
Potential energy is greatest at the highest point of the roller coaster, where the speed is momentarily zero.
7.
FLASHCARD QUESTION
Front
How does height affect potential energy?
Back
Potential energy increases with height; the higher an object is, the more gravitational potential energy it has.
