FLASHCARD QUESTION

Front

What is the formula for calculating gravitational potential energy (GPE)?

Back

GPE = m * g * h, where m is mass, g is acceleration due to gravity, and h is height.

What is the unit of gravitational potential energy?

Back

Joules (J)

FLASHCARD QUESTION

Front

What is kinetic energy (KE)?

Back

The energy an object possesses due to its motion, calculated as KE = 0.5 * m * v^2, where m is mass and v is velocity.

FLASHCARD QUESTION

Front

How does the height of an object affect its gravitational potential energy?

Back

The higher the object, the greater its gravitational potential energy.

6.

FLASHCARD QUESTION

Front

What happens to the total mechanical energy in a closed system?

Back

The total mechanical energy (sum of potential and kinetic energy) remains constant.

7.

FLASHCARD QUESTION

Front

What is the relationship between potential energy and kinetic energy in a pendulum?

Back

As the pendulum swings, potential energy decreases while kinetic energy increases, and vice versa.
