FLASHCARD QUESTION

Front

What does the Law of Conservation of Energy state?

Back

The total amount of energy is conserved before and after a reaction.

3.

FLASHCARD QUESTION

Front

What is the formula to calculate the velocity of an object just before it hits the ground?

Back

v = √(2gh), where g is the acceleration due to gravity and h is the height.

FLASHCARD QUESTION

Front

If a 30 kg crate is lifted to a height of 35m, what is its gravitational potential energy?

Back

Potential Energy = mgh = 30 kg * 9.81 m/s² * 35 m = 10285.5 joules.

FLASHCARD QUESTION

Front

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

Back

As kinetic energy increases, potential energy decreases, and vice versa, maintaining total energy conservation.
