FLASHCARD QUESTION
Front
Back
The formula for kinetic energy (KE) is KE = 1/2 mv², where m is the mass and v is the velocity.
2.
FLASHCARD QUESTION
Front
What is the kinetic energy of an object with a mass of 2 kg moving at a speed of 3 m/s?
Back
The kinetic energy is 9 J (KE = 1/2 * 2 kg * (3 m/s)²).

FLASHCARD QUESTION
Front
What is the definition of potential energy?
Back
Potential energy is the energy stored in an object due to its position or configuration.

FLASHCARD QUESTION
Front
What is the formula for calculating gravitational potential energy?
Back
The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
5.
FLASHCARD QUESTION
Front
How does height affect potential energy?
Back
Potential energy increases with height; the higher an object is, the more potential energy it has.
6.
FLASHCARD QUESTION
Front
What is the potential energy of a 5 kg object at a height of 10 m?
Back
The potential energy is 490 J (PE = 5 kg * 9.8 m/s² * 10 m).

FLASHCARD QUESTION
Front
What is the relationship between kinetic energy and velocity?
Back
Kinetic energy is proportional to the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.
