FLASHCARD QUESTION

Front

What is the definition of mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.

2.

FLASHCARD QUESTION

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

3.

FLASHCARD QUESTION

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, commonly calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

FLASHCARD QUESTION

Front

How do you calculate potential energy?

Back

Potential energy (PE) is calculated using the formula PE = mgh.

6.

FLASHCARD QUESTION

Front

What happens to mechanical energy in a closed system?

Back

In a closed system, the total mechanical energy remains constant, as energy is conserved.

7.

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.
