FLASHCARD QUESTION
Front
What is kinetic energy?
Back
Kinetic energy is the energy an object possesses due to its motion. It is directly proportional to the mass of the object and the square of its velocity.
2.
FLASHCARD QUESTION
Front
What is potential energy?
Back
Potential energy is the stored energy of an object based on its position or state. It is often associated with the height of an object in a gravitational field.
3.
FLASHCARD QUESTION
Front
What is the formula for calculating kinetic energy?
Back
The formula for kinetic energy (KE) is KE = 1/2 mv², where m is the mass of the object and v is its velocity.
4.
FLASHCARD QUESTION
Front
What is the formula for calculating potential energy?
Back
The formula for potential energy (PE) is PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height above a reference point.
5.
FLASHCARD QUESTION
Front
What happens to kinetic energy as the speed of an object increases?
Back
As the speed of an object increases, its kinetic energy increases exponentially because kinetic energy is proportional to the square of the velocity.
6.
FLASHCARD QUESTION
Front
What is the unit of measure for energy?
Back
The unit of measure for both potential and kinetic energy is the Joule (J).
7.
FLASHCARD QUESTION
Front
How does height affect potential energy?
Back
Potential energy increases with height; the higher an object is positioned, the greater its potential energy due to the gravitational force acting on it.
